▎ 摘　　要

NOVELTY - Preparing nitrogen-doped graphene-loaded iron-cobalt bimetallic single-atom catalyst comprises adopting the cooperative pyrolysis-impregnation reduction method, using disodium ethylenediaminetetraacetic acid as chelating agent to coordinate with nonahydrate and ferric nitrate to introduce iron single atoms into the system, and preparing the nitrogen-doped graphene supported iron and cobalt bimetallic single atom catalyst through the defect adsorption of cobalt single atom. USE - Th method is useful for preparing nitrogen-doped graphene-loaded iron-cobalt bimetallic single-atom catalyst. ADVANTAGE - The method: is economical, easy to control, and beneficial to industrial applications; and has high in uniformity, large output, and excellent repeatability.
