METHOD FOR PRODUCING HYDROGEN USING CADMIUM SULFIDE GROUPED PHOTO CATALYST FOR GENERATING HYDROGEN

摘要

PURPOSE: A photocatalyst for generating hydrogen is provided to activate the photo catalyst in a sunbeam area as well as in a visible ray area, to increase generating amount of hydrogen and to make the life span of the catalyst semi-permanent. CONSTITUTION: A photo catalyst is indicated as a chemical formula, m(A)/Cd(M(B))S. A method for producing the photo catalyst is composed of the steps of: dissolving a compound containing Cd and M to make mole % of M 0.05 to 20.00; stirring the dissolved compound after giving the compound H2S or Na2S as a reactor to gain a Cd£M|S deposit; cleansing the deposit with water until pH keeps 7; drying the cleansed deposit in a vacuum under a nitrogen atmosphere, and doping the deposit by giving the deposit liquid compound containing m to be 0/10 to 2.50wt% of m content. The m stands for doped metal.
