The present invention relates to the technical field of electrochemical catalysis and provides a ZIF-8-based nickel-iron-nitrogen-doped carbon material electrocatalyst having three functions, a preparation method therefor and application thereof.The ZIF-8-based nickel-iron-nitrogen-doped carbon material electrocatalyst having three functions provided in the present invention has a core-shell structure; the core layer is composed of nanoparticles containing iron and nickel elements, and the shell layer is composed of a nitrogen-doped carbon material. The core-shell structure of the electrocatalyst provided by the present invention can accelerate the electron transfer efficiency during a reaction process; the doping of iron, nickel, and nitrogen changes the electronic structure and morphology of the carbon material, so that the conductivity and catalytic active sites of the catalyst are improved. Therefore, the electrocatalyst provided by the present invention exhibits excellent multifunctional electrocatalytic performance, has good methanol tolerance and cycle stability, and has potential application value in technologies related to fuel cells, electrolysis of water, etc. |
