FIELD: chemistry.
SUBSTANCE: photocatalyst for obtaining hydrogen from a water solution of glycerol under impact of visible radiation with a composition: Pt/Cd1-xZnxS/ZnO/Zn(OH)2, where: x=0.5-0.9, a weight part of platinum constitutes 0.1-1%, is prepared from a mixture of solutions of cadmium and zinc salts, hydroxides of which are precipitated by addition of sodium hydroxide. After that, sulphidation of hydroxides with sodium sulphide is performed. The obtained sediment is dried at a temperature of 60-150°C, impregnated with a solution of H2PtCl6 in hydrochloric acid and reduced with NaBH4 solution.
EFFECT: invention makes it possible to increase the photocatalytic activity of the catalyst.
