▎ 摘  要

NOVELTY - A silver-ruthenium double metal doped graphene catalyst comprises a graphene carrier loaded with silver and ruthenium nanoparticles in a mass ratio of 0.5-1:0.6-1.1. The silver and ruthenium nanoparticles have a diameter of 100-800 nm. USE - Silver-ruthenium double metal doped graphene catalyst used in synthesis of bisphenol F and 1-phenyl-3-p-nitrophenyl acetone (all claimed). ADVANTAGE - The catalyst has excellent catalytic performance, can be recycled and reused, provides bisphenol with improved yield and reduced side products, and provides 1-phenyl-3-nitrophenyl acetone with chemical selectivity of 100% and yield of greater than 90%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the catalyst, which involves preparing graphene, dissolving silver tetrafluoroborate and ruthenium trichloride in glycol, adding graphene, adjusting pH of the mixed solution to 7-11, reacting under hydrothermal condition of 80-200 degrees C, cooling, centrifuging, washing, vacuum drying, roasting, and storing in a vacuum dryer.
