▎ 摘 要
NOVELTY - Method material comprises (i) dissolving nickel sulfate hexahydrate and 1,3,5-trimellitic acid into N,N-dimethylformamide in mixed solvent of deionized water and absolute ethanol, performing ultrasonic treatment and magnetically stirring to obtain a uniformly dispersed solution, (ii) transferring the mixed solution obtained in step (i) to a reaction kettle, and reacting, (iii) adding the mixed solution in a centrifuge tube and centrifuging to collect the precipitate, washing the precipitate and drying to obtain the metal organic framework MOF (Ni), (iv) dispersing graphene ultrasonically in the mixed solution obtained in the step (i), and transferring the resulting mixed solution to the reactor, and reacting, (vi) placing the mixed solution in a centrifuge tube to centrifuge to collect the precipitate, washing the obtained precipitate and then drying to obtain a metal organic framework and graphene composite material, and (vi) testing the synthesized material for hydrogen evolution. USE - The material is useful for hydrogen evolution. ADVANTAGE - The material has excellent hydrogen evolution performance under alkaline condition.
