▎ 摘　　要

NOVELTY - Transition metal hydroxide-graphene oxide composite material comprises graphene oxide loaded with transition metal hydroxide nanoparticle. USE - Transition metal hydroxide-graphene oxide composite material used for catalyzing oxygen evolution reaction in alkaline water electrolysis (claimed). ADVANTAGE - The transition metal hydroxide-graphene oxide composite material has uniform particle size and small particle diameter of transition metal hydroxide, thus, greatly improving catalytic property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of transition metal hydroxide-graphene oxide composite material comprising dispersing graphene oxide in solvent to form suspension, dissolving transition metal in solvent and preparing into solution, under stirring condition, dropwise adding the solution into the suspension, dropwise adding alkaline solution, reacting for 3-20 hours under stirring condition, obtaining precipitates, separating, washing, drying and obtaining the product.
