▎ 摘　　要

NOVELTY - Solvothermally preparing nitrogen-doped graphene-gold nano particle complex material by comprises ultrasonically dispersing graphite oxide in ethanediol containing urea, adding chloroauric acid solution, adjusting pH value of mixed liquid, placing the mixed liquid in the reaction kettle, reacting at a certain temperature for a period of time, while reducing the graphene oxide, nitrogen atom doping and depositing gold nanoparticles. USE - The method is useful in solvothermally preparing nitrogen-doped graphene-gold nano particle complex material (claimed). ADVANTAGE - The method is simple; does not need catalyst and additional reducing agent; is easy to control; does not require special equipment; is economical and easy to promote the use.
