	abstract = {TiO2-SiO2 mixed oxide materials were hydrothermally synthesized and the photocatalytic degrdn. of phenol under UV-irradn. was evaluated.  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.

	abstract = {Chromium contg. mesoporous silica materials were synthesized via a modified Stoeber synthesis at room temp.  The chromium ion loading and the effect of counterion in the synthesis were studied.  The mesoporous materials were extensively characterized by powder XRD, N2 physisorption, Atomic Absorption Spectroscopy (AAS), FTIR Spectroscopy (FTIR), Diffuse Reflectance Spectroscopy (DRS UV-visible), hydrogen Temp.-Programmed Redn. (H2-TPR), XPS, and TEM studies.  A transition from Ia3̅d cubic phase to p6mm hexagonal or wormhole phases was noted as more amts. of chromium were incorporated into the siliceous materials.  Chromium species present in the silica matrix include monochromate, polychromate, and chromium oxide (Cr2O3) clusters. [on SciFinder(R)]},

The authors demonstrate a relationship between the percentage surface content of Ti-O-Si and the rate of photocatalytic degrdn. of RhB.  The authors detailed surface investigation revealed that the overall degrdn. of RhB is enhanced due to the high surface percentage content of Ti-O-Si species, high crystallinity of titania phase, and its effective dispersion on a high surface area porous silica support.
