▎ 摘　　要

NOVELTY - A graphene layer is inserted into a mixed solution of chloroauric acid solution and graphene flakes and ultrasonic treatment is carried out, to obtain gold ions. A phytochemical solution comprising catechin, lycopene, isoflavone, lutein, astaxanthin and gallic acid is added to gold ion, gold ion is reduced to gold nanoparticles and chemical peeling is carried out to obtain gold nanoparticles-graphene composite. USE - Manufacture of gold nanoparticles-graphene composite used for electrical conductor. ADVANTAGE - The method economically and reliably provides gold nanoparticles-graphene composite.
