▎ 摘 要
NOVELTY - A three-dimensional honeycomb-like graphene non-metallic catalyst preparation method involves thoroughly mixing bean residue, sodium nitrate, first chloride salt and second chloride salt. The obtained mixture is carbonized under inert gas protection followed by washing with water to neutral and drying to obtain dried product. The dried product is soaked in acid for 12-24 hours. The soaked product is washed to neutral and dried. USE - Method for preparing three-dimensional honeycomb-like graphene non-metallic catalyst that is utilized as cathode oxygen reduction reaction (ORR) catalyst for fuel cell (claimed). ADVANTAGE - The method enables preparing three-dimensional honeycomb-like graphene non-metallic catalyst with high activity, specific surface area, large total pore volume, better oxygen reduction performance in alkaline solution and high resistance to methanol poisoning. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a three-dimensional honeycomb-like graphene non-metallic catalyst, which is prepared by the method.
