▎ 摘　　要

NOVELTY - Preparing graphene oxide coated zeolite imidazolate framework (ZIF-67) derived iron/cobalt/nitrogen/co-doped porous carbon nano-particle composite material, comprises (i) dissolving cobalt nitrate hexahydrate and ferric nitrate in methanol solution, stirring, adding graphene oxide suspension and continuously stirring to obtain the first mixed solution; (ii) taking dimethyl imidazole dissolved in methanol solution and stirring to obtain the second mixed solution;(iii) pouring the second mixed solution into the first mixed solution under the stirring condition and stirring to obtain the purple suspension; (iv) separating the obtained purple suspension liquid, drying, introducing into a tubular quartz furnace, heating and carbonizing under the protection of inert gas, cooling, to obtain the target product. USE - The material is useful for fuel cell cathode catalyst (claimed). ADVANTAGE - The composite material has excellent electrochemical performance, high initial potential, half-wave potential, high limit current density, excellent stability and anti-methanol performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene oxide coated zeolite imidazolate framework (ZIF-67) derived iron/cobalt/nitrogen/co-doped porouscarbon nano-particle composite material.
