NOVELTY - Nitrogen-phosphorus-doped graphene supported palladium catalyst comprises 3.12 plus minus 0.2% phosphorus, 7.41 plus minus 0.5% nitrogen, 2.93 plus minus 0.5% paladium, 72.65 plus minus 5% carbon, and rest is oxygen. USE - Nitrogen-phosphorus-doped graphene supported palladium catalyst. ADVANTAGE - The nitrogen phosphorus-doped graphene supported palladium catalyst is good for attaching metal, and has high conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing nitrogen phosphorus-doped graphene supported palladium catalyst, which involves preparing graphene oxide by Hummers method, firstly taking carbamide as nitrogen source, dipping in high pressure kettle and under protection of inert at 400-550 degrees C, doping high temperature pyrolysis, where phosphorus source is phosphoric acid, dipping in high pressure kettle and doping upper loading palladium metal by potassium borohydride under protection of inert at 500-650 degrees C high temperature pyrolysis to obtain nitrogen phosphorus-doped graphene supported palladium catalyst.
