▎ 摘 要
NOVELTY - A nitrogen doped graphene catalyst is prepared by taking glucose and urea, drying after dehydrating, mixing with melamine, grinding, putting in muffle furnace at 550 degrees C for sintering for 3 hours, cooling and grinding, putting in tubular furnace through nitrogen protection, and sintering at 850-1000 degrees C to obtain the catalyst. USE - Method for preparing nitrogen doped graphene catalyst for air cathode microbial fuel cell (claimed). ADVANTAGE - The method uses inexpensive raw materials. It is simple and has high yield.
