▎ 摘 要
NOVELTY - Preparing nitrogen-doped graphene oxygen reduction catalyst with high specific surface area comprises (i) dissolving carbon source, nitrogen source and sodium chloride in deionized water, heating magnetic stirring to obtain hydrogel, (ii) placing the gas gel in a tubular furnace, calcining under the protection of inert gas, and calcining for a period of time at the calcine temperature to obtain nitrogen-treated graphene chloride, and (iii) washing the nitrogen-treated graphene chloride and drying to obtain the final product. USE - The method for preparing nitrogen-doped graphene oxygen reduction catalyst with high specific surface area used as ORR catalyst of fuel cell or zinc air cell (claimed). ADVANTAGE - The method utilizes easily available raw materials, reproducible, low cost, simple preparation method, high yield, and easy for large scale industrial production.
