The catalyst synthesis method-resulting molecular structure relationships, stability and reactive transformations of the active site in response to gas phase environment, reaction mechanisms, reaction intermediates, the corresponding kinetics and effect of some popular promoters are covered. Key structural features of the active sites have been extensively investigated but the conclusive structure is yet to be determined due to the diversity of the preparation methods (nature and crystallinity of the support, sulfate deposition method, sulfate coverage) as well as the diversity of the experimental conditions used during the spectroscopic determination. Similarly, the effect of the promoters and the synergistic effects of the promoter/sulfate sites in the presence of hydrocarbons are not well-defined. Finally, multiple theories exist for the reactive mechanisms on sulfated zirconia but most rely on the homogeneous reaction mechanisms, such as those for ethylene dimerization and butane alkylation with butane. Collectively, these show the lack of a fundamental understanding and the need of modern catalysis studies of this important catalytic system.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Sharma, Lohit</style></author><author><style face="normal" font="default" size="100%">Brigaityte, Odeta</style></author><author><style face="normal" font="default" size="100%">Honer, Kenneth</style></author><author><style face="normal" font="default" size="100%">Kalfaoglu, Eren</style></author><author><style face="normal" font="default" size="100%">Slinksiene, Rasa</style></author><author><style face="normal" font="default" size="100%">Streimikis, Virginijus</style></author><author><style face="normal" font="default" size="100%">Sviklas, Alfredas Martynas</style></author><author><style face="normal" font="default" size="100%">Baltrusaitis, Jonas</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Carnallite-Derived Solid Waste as Potassium (K) and Magnesium (Mg) Source in Granulated Compound NPK Fertilizers</style></title><secondary-title><style face="normal" font="default" size="100%">ACS Sustainable Chemistry &amp; Engineering</style></secondary-title><short-title><style face="normal" font="default" size="100%">ACS Sustainable Chem.

While sour natural gas is still treated using energy-intensive amine absorption/desorption, here we propose and describe a first step in catalytically producing a value added chemical and energy carrier, CH3SH and H2, respectively. For this purpose, we performed Density Functional Theory (DFT) and microkinetic modelling of CH4 and H2S reaction pathways to form CH3SH and H2 as a first step in elucidating complex yet not explored pathways in oxygen-free sour gas reforming. For this purpose, we utilized bare unpromoted and K- or Ni-promoted Mo6S8 clusters. CH4 dissociation was found to be the rate-determining step above 1100 K on Ni-promoted Mo6S8 while H2 formation was the rate-determining step on the bare and K-promoted Mo6S8. At lower reaction temperatures between 800 and 1100 K, CH3SH formation becomes an important step, especially on Ni-Mo6S8. This method presents an interesting route of direct catalytic sour natural gas processing which potentially leads to high-value hydrocarbons, such as ethylene, using CH3SH as a reactive intermediate.</style></abstract><issue><style face="normal" font="default" size="100%">16</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Zabeti, Masoud</style></author><author><style face="normal" font="default" size="100%">Baltrusaitis, Jonas</style></author><author><style face="normal" font="default" size="100%">Seshan, K.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Chemical routes to hydrocarbons from pyrolysis of lignocellulose using Cs promoted amorphous silica alumina catalyst.</style></title><secondary-title><style face="normal" font="default" size="100%">Catalysis Today</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">hydrocarbon pyrolysis lignocellulose cesium promoted amorphous silica alumina catalyst</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2016</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2016</style></date></pub-dates></dates><publisher><style face="normal" font="default" size="100%">Elsevier B.V.</style></publisher><volume><style face="normal" font="default" size="100%">269</style></volume><pages><style face="normal" font="default" size="100%">156 - 165</style></pages><isbn><style face="normal" font="default" size="100%">0920-5861</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">Lignocellulos biomass can be converted to bio-oil contg. aliph. hydrocarbons via catalytic pyrolysis at 500 °C in the presence of Cs modified amorphous silica alumina (Cs/ASA).  The reaction routes for the formation of aliph. hydrocarbons was studied using biomass constituent, viz. cellulose, hemicellulose, lignin, and single model components in a pyrolyzer system in conjunction with GC/MS.  The pyrolysis behavior of each biomass constituent was also studied using TGA.  The results showed that in the presence of Cs/ASA catalyst aliph. hydrocarbons can be formed from all the three constituents but mainly from lignin (35% of total peak area compared to 10% for cellulose) resulting in high quality bio-oil with 40 Mj kg-1 heating value.  On the other hand, the pyrolysis of single model compds. did not result in the aliph. hydrocarbons.  However, pyrolysis of mixt. of the model compds. yielded in aliph. hydrocarbons indicating effect of intermol. interactions such as hydrogen transfer over Cs+ ions.

The pp-HMDSO films were deposited on a soda-lime-silica float glass using HMDSO monomer vapor as a precursor.  A detailed surface characterization was performed using SEM and at. force microscopy.  The growth process of the pp-HMDSO films was investigated as a function of deposition time from 30 to 300 s.  The non-wetting characteristics of the pp-HMDSO films were evaluated by means of contact angle (CA) measurements and correlated with the morphol. characteristics, as obtained from microscopy measurements.  The deposited films were found to be nano-structured and exhibited dual-scale roughness with the static CA values close to 170°.  Fourier transform IR spectroscopy anal. was carried out to investigate chem. and functional properties of these films.  Me groups were identified spectroscopically to be present within the pp-HMDSO films and were proposed to result in the low surface energy of material.  The synergy between the dual-scale roughness and low surface energy resulted in the superhydrophobic characteristics of the pp-HMDSO films.  A possible mechanism for the pp-HMDSO film formation is proposed.

We also demonstrated that varying the co-solvent, modulates the structural properties of the materials.  In particular, the use of non-polar co-solvents such as toluene seemed to increase the crystallinity, surface area, and pore diam. while the crystallite size of titania seemed to change little.  A comprehensive characterization using surface and bulk techniques evidenced the role of porosities, crystallinity, and Ti-O-Si linkages of the mixed oxides as significant factors that contribute to the degrdn. of phenol.  The TiO2-SiO2 mixed oxide material prepd. using only ethanol as the solvent showed 24% degrdn. of phenol after 120 min of irradn. whereas other mixed oxide materials degraded phenol more efficiently (57% to 100%) in the same duration of time.  The higher photocatalytic activities of the mixed oxide materials prepd. using non-polar solvents is attributed to a combination of factors that include higher Apparent Surface Coverages of Ti-O-Si heterolinkages, larger pore sizes, and most importantly higher crystallinities of the titania phase.  Larger pore sizes enabled better transport of reactant mols. and products to and from the active sites (Ti-O-Si heterolinkages) and the higher crystallinities of the titania phase helped in minimizing the electron-hole recombination in these photocatalysts, and thus resulted in high degrdn. efficiencies.

Since free iron concns. are extremely low in airway surface liq. (ASL), we hypothesize that CFA impairs antimicrobial peptides (AMP) function and can be a source of iron to bacteria.  We tested this hypothesis in vivo by instilling mice with Pseudomonas aeruginosa (PA01) and CFA and det. the percentage of bacterial clearance.  In addn., we tested bacterial clearance in cell culture by exposing primary human airway epithelial cells to PA01 and CFA and detg. the AMP activity and bacterial growth in vitro.  We report that CFA is a bioavailable source of iron for bacteria.  We show that CFA interferes with bacterial clearance in vivo and in primary human airway epithelial cultures.  Also, we demonstrate that CFA inhibits AMP activity in vitro, which we propose as a mechanism of our cell culture and in vivo results.  Furthermore, PA01 uses CFA as an iron source with a direct correlation between CFA iron dissoln. and bacterial growth.  CFA concns. used are very relevant to human daily exposures, thus posing a potential public health risk for susceptible subjects.  Although CFA provides a source of bioavailable iron for bacteria, not all CFA particles have the same biol. effects, and their propensity for iron dissoln. is an important factor.  CFA impairs lung innate immune mechanisms of bacterial clearance, specifically AMP activity.  We expect that identifying the PM mechanisms of respiratory infections will translate into public health policies aimed at controlling, not only concn. of PM exposure, but physicochem. characteristics that will potentially cause respiratory infections in susceptible individuals and populations.

Few measurements have been made that compare the soly. of atm. iron from anthropogenic aerosols and other sources.  We report here an investigation of iron dissoln. for three FA samples in acidic aq. solns. and compare the solubilities with that of Arizona test dust (AZTD), a ref. material for mineral dust.  The effects of pH, simulated cloud processing, and solar radiation on iron soly. have been explored.  Similar to previously reported results on mineral dust, iron in aluminosilicate phases provides the predominant component of dissolved iron.  Iron soly. of FA is substantially higher than of the cryst. minerals comprising AZTD.  Simulated atm. processing elevates iron soly. due to significant changes in the morphol. of aluminosilicate glass, a dominant material in FA particles.  Iron is continuously released into the aq. soln. as FA particles break up into smaller fragments.  These results suggest that the assessment of dissolved atm. iron deposition fluxes and their effect on the biogeochem. at the ocean surface should be constrained by the source, environmental pH, iron speciation, and solar radiation.

(RSC), H2S and CH3SH, were investigated using ground and excited state d. functional theory (DFT) and coupled cluster (CC) methods to explore possible RSC oxidn. mechanisms and CO2 activation mechanisms in the atm. environment.  Ground electronic state calcns. at the CR-CC(2,3)/6-311+G(2df,2p)//CAM-B3LYP/6-311+G(2df,2p) level show proton transfer as a limiting step in the redn. of CO2 with activation energies of 49.64 and 47.70 kcal/mol, resp., for H2S and CH3SH.  On the first excited state surface, CR-EOMCC(2,3)/6-311+G(2df,2p)//CAM-B3LYP/6-311+G(2df,2p) calcns. reveal that energies of &lt;250 nm are needed to form H2S-CO2 and CH3SH-CO2 complexes allowing facile hydrogen atom transfer.  Once excited, all reaction intermediates and transition states are downhill energetically showing either C-H or C-S bond formation in the excited state whereas only C-S bond formation was found in the ground state.  Environmental implications of these data are discussed with a focus on tropospheric reactions between CO2 and RSC, as well as potential for carbon sequestration using photocatalysis.

In the absence of water vapor (&lt;1% relative humidity, RH), following exposure to CO2 different species formed on the oxide surface due to the presence of adsorption sites with different basicities.  While the majority surface species on Fe2O3, γ-Al2O3 is detd. to be adsorbed bicarbonate, on TiO2 nanoparticles bidentate carbonate was more prevalent.  A carboxylate species was obsd. on TiO2 nanoparticles under dry conditions as well.  When water is present at 40% RH, the nature of the adsorbed CO2 species changed to that of solvated carbonate formation in the adsorbed water layer.  Obsd. initial adsorption rates were calcd. from time-course expts. under dry conditions and in the presence of 40% RH.  When initial adsorption rates were compared between dry and wet expts., a larger value was found for dry expts. suggesting that CO2 mols. have to compete for adsorption sites with water on these nanoparticle surfaces.  As discussed here, quantum chem. calcns. provide some addnl. insights into CO2 adsorption on hydroxylated metal oxide surfaces in the presence and absence of molecularly adsorbed water.

Soln. NMR spectroscopy and quantum chem. calcns. support the isomerization to generate two diastereomers.  The NMR data, however, could not lead to unambiguous configurational assignments of the two isomers.  Single-crystal X-ray diffraction was employed to det. each configuration.  One isomer readily crystd. as a pure form and X-ray diffraction revealed the mol. as being achiral based on Ci symmetry.  The second isomer resisted crystn. under a variety of conditions.  Consequently, a strategy based on a cocrystn. was developed to generate single crystals of the second isomer.  Cocrystn. of the isomer with a carboxylic acid readily afforded single crystals that confirmed a chiral ladderane based on C2 symmetry.  The chiral ladderane and acid self-assembled to generate a five-component hydrogen-bonded complex that packs to form large solvent-filled homochiral channels of nanometer-scale dimensions.  Whereas cocrystns. are frequently applied to structure detns. of proteins, our study represents the first application of a cocrystn. to confirm the relative configuration of a small-mol. diastereomer generated in a soln.-phase org. synthesis.

Force Microscopy (AFM) height images combined with force measurements and phase imaging were used to investigate the surface reconstruction and chem. of the lowest energy surface, ( 1 0 1 4 ) plane, of calcite, a stable form of calcium carbonate (CaCO3), in the presence of relative humidity at different temps.  At 296 K and 70% RH, calcite ( 1 0 1 4 ) undergoes rapid restructuring during hydration forming regions on the surface that are most likely characterized as an amorphous hydrate layer similar to what forms in soln. under high [Ca2+] supersatn. conditions.  This hydrate layer in turn serves as a substrate for the crystn. of another layer that possesses structural properties which differ from hydrate layer.  Phase imaging reveals that these different layer structures formed in the process of water adsorption and surface reconstruction have very different energy dissipation modes.  The origin of the different dissipation modes are likely due to differences in water content and hydrophobicity of these regions.  The newly formed layer on top of the hydration layer is proposed to be vaterite, another polymorph of CaCO3.  At 278 K the formation mechanism of the vaterite layer changes due to nucleation of a more cryst. hydrate layer, similar to CaCO3 hexahydrate, instead of the amorphous hydrate layer that forms at 296 K.  Force measurements corroborate the assignment of the speciation of different regions on the surface.  Importantly, the AFM data show that the surface of calcite is highly inhomogeneous with regions that vary in water content.  The reactivity of calcite in humid environments will be highly spatially dependent.

In particular, the uptake of acids such as H2SO4 and HNO3 on mineral dust surfaces can produce extremely acidic environments that promote iron dissoln.  Here, four samples that represent source materials for mineral dust (Saudi Beach sand (SB), Inland Saudi sand (IS), Saharan Sand (SS) and China Loess (CL)) and one com. ref. material (Arizona Test Dust (AZTD)) were characterized, and examd. in dissoln. studies in solns. of sulfuric, nitric and hydrochloric acid ranging from pH 1 to 3.  Mossbauer spectroscopy revealed Fe(III) in all samples, whereas SB, CL and AZTD also contained appreciable Fe(II).  Spectra suggest that both Fe(II) and Fe(III) were substituted into aluminosilicates, although CL, AZTD and IS also contained Fe(III) oxide phases.  Total iron soly. measured after 24 h ranged between 4-16% of the initial iron content for each material, but did not scale with either the sp. surface area or the total iron content of the samples.  Instead, we show that Fe(II)-contg. solid phases such as Fe(II)-substituted aluminosilicates represent a significant, and sometimes dominant, source of sol. Fe in acidic environments.  Results of dissoln. studies also show that the nature of the acid influences iron solubilization, as elevated concns. of nitrate encountered from nitric acid at pH 1 suppressed Fe(II) formation.  We propose a surface-mediated, non-photochem. redox reaction between nitrate and Fe(II), which may contribute to Fe(II)/Fe(III) cycling in the atm.
