▎ 摘  要

NOVELTY - Composite material comprises platinum-loaded graphene oxide and copper-based metal organic framework. The copper-based metal organic framework is constructed by coordinately bonding copper ions and bidentate ligand. The bidentate ligand is trimesic acid. USE - The composite material is useful as hydrogen storage material (claimed). ADVANTAGE - The composite material has high-temperature hydrogen storage capacity and good test controllability. The method is economical and has simple preparation process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the composite material, comprising: (i) dissolving soluble copper salt and trimesic acid solution in N,N'-dimethyl formamide, and adding ethanol and deionized water under stirring conditions; (ii) adding platinum-loaded graphene oxide to the mixed solution obtained in step (i), uniformly stirring, and ultrasonically dispersing to obtain the reaction solution; and (iii) performing solvothermal reaction of the reaction solution under programmed temperature control, soaking the product, filtering, centrifuging and drying to obtain the product.
