▎ 摘　　要

NOVELTY - Preparing porous graphene-loaded cobalt iron sulfide catalyst comprises using graphene oxide, melamine, formaldehyde, cobalt source and iron source by hydrothermal reaction to obtain a graphene hydrogel, mixing the graphene hydrogel and the sulfur source fully, performing high-temperature heat treatment under the protection atmosphere to obtain porous graphene loaded cobalt-iron sulfide powder material, washing the powder with acid washing and secondary heat treatment to obtain the porous graphene laden cobalt sulfide catalyst. The porous graphene load cobalt sulfide catalysts are a core-shell structure, and the particle size is 21-24 nm. USE - The catalyst is useful in fuel cell and zinc-air cell electrode material of alkaline reaction system. ADVANTAGE - The catalyst: exhibits excellent catalytic activity and stability; and can be applied to fuel cell and zinc-air cell electrode material.
