▎ 摘　　要

NOVELTY - A metal-solid acid double-site catalyst contains acid site and metal site double center. The acid center is sulfonated graphene with two-dimensional planar structure. The metal center has higher carbon-oxygen hydrogen-active metal ruthenium. USE - Metal-solid acid double-site catalyst. ADVANTAGE - The catalyst exhibits excellent catalytic performance in direct preparation of furfuryl alcohol by one-step method of catalyzing xylose through dehydration-hydrogenation. The reaction is simple. The catalyst can be recycled. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the metal-solid acid dual-site catalyst comprises subjecting graphene to sulfonation modification to give graphene rich protonic acid sites on two-dimensional plane. The metal ruthenium with high catalytic activity and good stability in water phase supported on surface of sulfonated graphene is metal hydrogenation site.
