▎ 摘　　要

NOVELTY - Preparation of reduced graphene supported molybdenum carbide or tungsten catalyst, involves performing one-pot synthesis of acid-polymer conductors/reducing graphene composite using molybdenum or tungsten heteropolyacids, polymer conductor and graphene material, and heat treating at 700-1100 degrees C for 2-5 hours, under the protection of inert gas, and cooling, acid washing the product, to obtain graphene supported molybdenum carbide or tungsten catalyst. USE - Preparation of reduced graphene supported molybdenum carbide or tungsten catalyst used for hydrogen production by water electrolysis (all claimed). ADVANTAGE - The preparation process of catalyst is simplified. The unique structure is provided, so as to limit the reunion molybdenum or tungsten carbide nano-particles and enhance the dispersion. The hydrogen production performance is excellent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for reduced graphene supported molybdenum carbide or tungsten catalyst.
