NOVELTY - A metal/graphene catalyst comprises 1-30% metal and graphene. USE - As metal/graphene catalyst (claimed) for hydrogenation, reforming and catalytic reaction. ADVANTAGE - The catalyst is prepared with method simple and with controlled metal particle size. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of metal/graphene catalyst involving: ultrasonically dispersing 0.1-100% metal salt and graphene in a mass ratio of 100 in organic amine for 5-300 minutes at 10-300 W, where the organic amine and the metal salt is in a mass ratio of 50-50000:1; heating the dispersed solution at 100-300 degrees C for 0.5-24 hours, and filtering, washing and drying to obtain metal/graphene catalyst.
