Abstract
Films of polycrystalline Bi{sub 2}S{sub 3} have been prepared onto bismuth and platinum substrates by electrodeposition from an aqueous sulfide bath. The films were thin, uniform and well adhered. Bi{sub 2}S{sub 3} is a direct band gap semiconductor with a value of 1.28eV optimally matched with the solar spectrum. The photoelectrochemical study was undertaken for the generation of hydrogen by using illuminated n-Bi{sub 2}S{sub 3} particles; it was found that hydrogen evolution depends highly on the synthesis method of powder. Impregnation of platinum onto Bi{sub 2}S{sub 3} shows a production enhancement of about 25%. The most active photocatalyst, prepared by a solvent thermal process and loaded with Pt in 0.1MS{sup 2-} alkaline electrolyte, yields 2.13x10{sup -2}mlmg{sup -1} of H{sub 2} after 4h of irradiation with the visible output of a 500W halogen lamp.
