▎ 摘 要
NOVELTY - Rapid preparation of graphene-supported polymetallic catalyst involves preparing graphene oxide powder, adding aqueous solution of metal salts, ultrasonically-processing in water bath at 25 degrees C for 10 minutes, drying at 60 degrees C in oven to obtain a graphene-supported polymetallic catalyst precursor, crushing precursor, heating and cooling to room temperature. USE - Rapid preparation of graphene-supported polymetallic catalyst (claimed). ADVANTAGE - The method enables simple and rapid preparation of graphene-supported polymetallic catalyst with uniform particle size distribution.
