▎ 摘 要
NOVELTY - A metal organic framework/graphene oxide hydrogen storage material has 1.0-5.0%mass noble metal precursor impregnated in metal organic framework/graphene oxide carrier. The metal organic framework is zeolitic imidazolate framework (ZIF-8). USE - Metal organic framework/graphene oxide type hydrogen storage material. ADVANTAGE - The material has excellent hydrogen storage performance at room temperature, and is manufactured by a simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of metal organic framework/graphene oxide type hydrogen storage material, which involves dissolving soluble zinc salt, 2-methyl imidazole and graphene oxide in 8.9-12.8 g/L methanol, heating the mixture, and impregnating soluble palladium salt on the carrier in presence of reducing agent and dispersant . The soluble zinc salt is zinc nitrate, zinc sulfate, zinc acetate or zinc chloride. The ratio of soluble zinc salt and 2-methyl imidazole is 1:1.7-2.8. The graphene oxide is added in the ratio of 5 %mass. The reducing agent is sodium borohydride, potassium borohydride or hydrazine hydrate. The dispersant is polyvinyl alcohol.
