▎ 摘　　要

NOVELTY - Nano silver-loaded graphene aerogel comprises graphene substrate and nano silver which is supported on graphene substrate. USE - Nano silver-loaded graphene aerogel for improving the rate of nitro-catalyzed conversion of aromatic ring (claimed) environmental protection and chemical industry. ADVANTAGE - The nano silver-loaded graphene aerogel that is convenient to use, has high catalytic performance and ultra-high catalytic conversion rate, and in eco-friendly manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing nano silver-loaded graphene aerogel, which involves: (A) dispersing graphene oxide in water, adding reducing agent A to form reducing environment; and (B) adding silver-ammonia solution, adding reducing agent B, reducing silver ions to nano silver, reducing graphene oxide into graphene hydrogel, and drying to obtain nano silver-loaded graphene aerogel.
