▎ 摘　　要

NOVELTY - Preparing catalytic hydrogenation catalyst based on double-network graphene hydrogel comprises(a) polymerizing graphene containing palladium ions and double bonds and acrylic acid and acrylamide to obtain a first layer network, (a2) immersing it in a natural anionic polymer aqueous solution to form a second layer network, (a3) reducing sodium borohydride to obtain a catalytic hydrogenation catalyst based on double-network graphene hydrogel. USE - The method is useful for preparing catalytic hydrogenation catalyst based on double-network graphene hydrogel. ADVANTAGE - The method promotes the forward process of catalytic hydrogenation.
