NOVELTY - The method involves adding nickel acetate tetrahydrate, cobalt nitrate hexahydrate, and graphene in sequence to the continuously stirred methanol solution to obtain first solution. The amount of methanol solution used should ensure that the components are completely dissolved. The dimethylimidazole is added to first solution in batches, The added in batches ensure that the last addition is completely dissolved before the next addition is performed to ensure that the second Methyl imidazole is fully dispersed. The third mixture is uniformly grinded, so as to place in a tube furnace for calcination. The third mixture is washed and dried to obtain a MOF-derived cobalt nickel carbide-nitrogen-doped graphene composite catalytic material. USE - Preparation of double-metal organic framework (MOF) composite nitrogen-doped graphene catalytic material for direct methanol fuel cell (DMFC) used as energy converter of flexible electronic device. ADVANTAGE - The obtained composite catalytic material has a high specific surface area and excellent dispersibility of metal particles, so as to provide a guarantee for high catalytic activity. The excellent alcohol oxidation activity exhibits in a mixed solution of 1.0M methanol and 0.5M sulfuric acid at a sweep rate of 30mV/s. The material maintains 78.3% of the initial value after 1000 cycles, so as to show very good stability.
