▎ 摘　　要

NOVELTY - Preparation of graphene quantum dot-modified gold nanoparticles involves adding chloroauric acid, graphene quantum dots as additive, and sodium citrate as reducing agent in boiled aqueous solution. The concentration of aqueous solution of graphene quantum dots is 0.1-100 mg/mL. The concentration of chloroauric acid is 1mM. USE - Preparation of graphene quantum dot-modified gold nanoparticles used for preparing alcohol oxidation catalyst (claimed). ADVANTAGE - The method enables preparation of graphene quantum dot-modified gold nanoparticles with uniform and stable particle distribution, by simple process.
