Manufacturing method of CdS photocatalyst for hydrogen production and method for producing hydrogen by use of the same

摘要

A method for preparing a CdS photocatalyst represented by general formula (I): m(a)/CdM(b)S, comprising the steps of: dissolving Cd-containing and M-containing compounds in water in such an amount that the mol % of M ranges from 0.001 to. 20.00; adding one H₂S or Na₂S as a reactant in the solution with stirring to precipitate CdMS; washing the precipitate with water and vacuum-drying the precipitate in a nitrogen environment at a temperature of 105150 C. for 1.53.0 hours; doping a liquid m-containing compound to this precipitate in such an amount that the % by weight of m ranges from 0.10 to 5.00. In the formula, m represents a doped metal element as an electron acceptor selected from the group of Ni, Pd, Pt, Fe, Ru, Co or an oxidized compound of these metals; a represents a percentage by weight of m, ranging from 0.10 to 5.00; M is a promoter selected from the group consisting of V, Cr, Al, P, As, Sb and Pb; b represents mol % of M/(MCd), ranging from 0.001 to 20.00.
