	abstract = {Semiconducting tin sulfide (SnS) was deposited electrochem. from electrolytes contg. Sn and S precursors and conditions optimized to maximize its performance as a photoelectrode.  Films composed of primarily orthorhombic SnS were electrodeposited on titanium substrates from electrolyte contg. 20 mM SnSO4 and 100 mM Na2S2O3 at pH 2.5.  For deposition a cathodic pulse of -1.25 V vs Ag/AgCl was applied for 2.75 s followed by a 0.25 s pulse of +0.25 V vs Ag/AgCl repeated for 30-45 min.  The films were annealed in argon at 300 {\textdegree}C for 3 h.  The addn. of SbCl3 (<5\%) to the electrolyte gave rise to doping of the SnS film with Sb which resulted in an increase in the photocurrent as well as a switch from p- to n-type semiconducting behavior in an acidified Na2S2O3 electrolyte.  Incorporation of p-type In into the films from addn. of In(NO3)3 had a smaller effect on the measured photocurrent, and at higher precursor concn. (>5\%) the dopants resulted in the formation of secondary phases of Sb and In oxides with redn. in the measured photocurrent.  This doped SnS material could potentially be used in systems for the photoelectrochem. prodn. of hydrogen and oxidn. of org. wastewater.  D. functional theory calcns. supported the exptl. obsd. cond. increase for photoelectrons as an Sb dopant induced curvature of the valence band.  These calcns. also provided an explanation to the previous exptl. work where Sb doping was used to decrease the resistivity of SnS films.  The combination of an automated electrodeposition of an earth abundant metal sulfide with the theor. calcns. to guide the synthesis is an exemplar of how to improve the efficiency of SnS-based solar energy conversion materials.

	abstract = {Mixed metal sulfides contg. combinations of W, Fe, Mo, Ni, and Ru were synthesized and screened for activity and stability for the H evolution reaction (HER) in aq. HBr.  Co- and Ni-substituted RuS2 were identified as potentially active HER electrocatalysts by high-throughput screening (HTS), and the specific compns. Co0.4Ru0.6S2 and Ni0.6Ru0.4S2 were identified by optimization.  H evolution activity of Co0.4Ru0.6S2 in HBr is greater than RuS2 or CoS2 and comparable to Pt and com. RhxSy.  Structural and morphol. characterizations of the Co-substituted RuS2 suggest that the nanoparticulate solids are a homogeneous solid soln. with a pyrite crystal structure.  No phase sepn. is detected for Co substitutions <30\% by x-ray diffraction.  In 0.5 M HBr electrolyte, the Co-Ru electrode material synthesized with 30\% Co rapidly lost \~{}34\% of the initial loading of Co; thereafter, it was obsd. to exhibit stable activity for HER with no further loss of Co.  D. functional theory calcns. indicate that the S22- sites are the most important for HER and the presence of Co influences the S22- sites such that the H binding energy at sufficiently high H coverage is decreased compared to Ru sulfide.  Although showing high HER activity in a flow cell, the reverse reaction of H oxidn. is slow on the RuS2 catalysts tested when compared to Pt and Rh sulfide, leaving Rh sulfide as the only suitable tested material for a regenerative HBr cell due its stability compared to Pt.

	abstract = {The dependence of electrooxidn. on exptl. conditions of org. mols. was investigated to optimize the prodn. of hydrogen from potential wastewater sources using low voltage sources (\~{}1 V dc).  Electrooxidn. on platinum, gold, and stainless steel anodes with hydrogen prodn. on the cathode was investigated using several different org. reductants, including: methanol, ethanol, glycerol, isopropanol, propanal, glycerol, glucose, sucrose, citric acid, and propionic acid.  The electrolyte pH was varied from 2 to 12 in a 1 M Na2SO4 supporting soln.  At 1 V, glycerol, citric acid, ethanol and methanol were found to yield the highest currents at low pH values (pH 2 and 7) on platinum electrode, glucose on gold electrode at pH 12 in 1 M Na2SO4 soln. produced the highest total c.d. at 1 V with measured Faradaic efficiency for 1 M glucose of 70\%.  The hydrogen energy prodn. efficiency was 86\%.  Practical limitations of glucose oxidn. at optimum exptl. conditions are discussed. [on SciFinder(R)]},
