NOVELTY - Preparing hydrogen producing catalyst without taking noble metal as assistant catalyst, comprising cadmium sulfide-graphene composite material and titanium dioxide-graphene composite material, is claimed. USE - The method is useful for preparing hydrogen producing catalyst. ADVANTAGE - The method is simple, economical, environment-friendly and suitable for industrial production. The graphene material has good electronic gathering and transmission functions, promotes the effective separation of electrons and holes, reduces the probability of the proton complexes and increases the photo-catalyzing efficiency and optical hydrogen production efficiency.
