▎ 摘　　要

NOVELTY - A graphene oxide (GO) composite material is prepared by adding transition metal-containing powder (MA) to aqueous solution of GO to obtain mixed liquid, and performing ultrasonic treatment to obtain dispersion liquid containing MA/GO, in which M is transition metal; and taking the dispersion liquid for low speed centrifuging, taking the supernatant, taking the obtained precipitate and dispersing in water, and obtaining MA/GO aqueous solution. USE - Method for preparing graphene oxide composite material (claimed). ADVANTAGE - The method produces material having adjustable structure and good stability in aqueous solution.
