▎ 摘　　要

NOVELTY - Preparing gold nanoparticle loaded graphene aerogel comprises mixing graphene oxide, water, isopropyl alcohol and gold source to obtain a dispersion, irradiating the dispersion to obtain gold nanoparticle loaded graphene hydrogel, and freeze drying the graphene hydrogel to obtain gold nanoparticle loaded graphene aerogel. USE - The aerogel is useful for industrial synthesis of metallic nanoparticle/graphene composite high efficient catalyst. ADVANTAGE - The aerogel has a density of 3-10 mg/cm3 and gold particle diameter of 5-20 nm (claimed). The method has mild condition and easy operation, and is environmentally friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the gold nanoparticle loaded graphene aerogel prepared by the above method.
