▎ 摘　　要

NOVELTY - Catalytic material comprises graphene and double-coordinated iron single atoms, where the graphene is used as the conductive and load base body of the catalytic material, and the double-coordination iron single atom is monoatomic iron atoms coordinated with nitrogen and oxygen atoms, and loaded on the graphite alkenyl body. USE - The catalytic material is used in the alkaline electro-catalysis oxygen reduction reaction (claimed). ADVANTAGE - The material exhibits high power density and excellent discharge stability in the alkaline zinc-air battery, and solves the problem of high cost and bad cycle stability of oxygen reduction electrocatalytic materials for zinc-air batteries. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of catalytic material.
