▎ 摘　　要

NOVELTY - Preparation of nitrogen-doped pore graphene loaded with cobalt involves mixing aqueous dispersion of graphene oxide, and ascorbic acid, heating at 70-100 degrees C for 1-5 hours to obtain graphene aerogel, dialyzing graphene aerogel in ultrapure water, immersing in polyacrylic acid aqueous solution, heating at 60-120 degrees C for 1-5 hours, preferably 80-100 degrees C for 2-4 hours, removing from the solution, dialyzing in ultrapure water, immersing in aqueous solution of cobalt chloride, heating at 60-120 degrees C for 1-5 hours, preferably 80-100 degrees C for 2-4 hours, lyophilizing, and calcining at 700-1000 degrees C. USE - Preparation of nitrogen-doped pore graphene loaded with cobalt. ADVANTAGE - The nitrogen-doped pore graphene loaded with cobalt has unique structure, excellent stability, and excellent oxygen reduction reaction catalytic activity and stability in alkaline potassium hydroxide solution. The nitrogen-doped pore graphene loaded with cobalt is prepared by simple, and economical method.
