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 °C for 3 h.  The addn. of SbCl3 (&lt;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. (&gt;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.

(PEC) decompn. of org. compds. in wastewater is investigated by using quantum chem. (DFT) methods to evaluate alternatives to water splitting for the prodn. of renewable and sustainable hydrogen.  Methanol is used as a model org. species for the theor. evaluations of electrolysis on the surface of the widely available semiconductor hematite, α-Fe2O3, a widely studied photocatalyst.  Three different α-Fe2O3 surface terminations were investigated, including the predominant surface found in aq. electrolytes, (OH)3-R.  The PEC oxidn. of methanol is energetically downhill, producing CO2 and protons.  The protons are reduced to hydrogen on the cathode.  Exptl. PEC measurements were also performed for several polyalcoholic compds., glycerol, erythritol, and xylitol, on α-Fe2O3 as the photocatalyst and showed high incident-photon-to-current-efficiencies (IPCE) that were much greater than those of water splitting.  Interestingly, high IPCEs were obsd. for hydrogen prodn. from polyalcs. in the absence of any applied bias, which was not thought to be possible on hematite.  These results support the potential application of PEC for hydrogen prodn. by using widely available hematite for the PEC oxidn. of selected components of org. wastewater present in large quantities from anthropogenic and industrial sources.

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.
