NOVELTY - Preparation of nitrogen-doped graphene airgel load non-precious metal oxygen reduction catalyst comprises adding organic amine and aldehyde into deionized water, stirring to obtain prepolymer; adding graphene oxide solution and non-precious metal salt solution, stirring to obtain organic gel, freezing or supercritical drying to obtain nitrogen-doped graphene airgel load non-precious oxygen reduction catalyst precursor; and placing precursor in porcelain boat, heating under inert gas protection, incubating for 1-6 hours, and cooling to room temperature. USE - Method for preparing nitrogen-doped graphene airgel load non-precious metal oxygen reduction catalyst (claimed). ADVANTAGE - The method is simple and inexpensive. DETAILED DESCRIPTION - Preparation of nitrogen-doped graphene airgel load non-precious metal oxygen reduction catalyst comprises adding organic amine and aldehyde at mass ratio of 1:9 into deionized water, stirring at 50-90 degrees C for 0.5-2 hours to obtain prepolymer; adding 1-30 wt.% graphene oxide solution and 19-30 wt.% non-precious metal salt solution, stirring at 60-99 degrees C for 1-24 hours to obtain organic gel, freezing or supercritical drying to obtain nitrogen-doped graphene airgel load non-precious oxygen reduction catalyst precursor; and placing precursor in porcelain boat, heating under inert gas protection to 500-1000 degrees C at 1-10 degrees C/minute, incubating for 1-6 hours, and cooling to room temperature.
