Graphene is a two-dimensional honeycomb lattice structure carbon material with a single layer of carbon, which was discovered in 2004. It has excellent electrical, thermal and optical properties and has attracted the attention of a wide range of scientific researchers. The research of graphene composites has become a hot spot. In this paper, some metal oxides, metal hydroxides and (oxidized) graphene composites were prepared by electrostatic attraction mechanism using graphite oxide precursor. The main contents are as follows: 1. Based on the characteristics of graphite oxide solution, the negatively charged graphene oxide was stripped by ultrasonic wave, combined with zinc, and ZnO nanoparticles were combined with graphene oxide by rapid precipitation in water-ethanol medium, and the photocatalytic degradation experiment of GO-ZnO nanocomposite (methylene blue) was obtained. The degradation amount is as high as 92%. 2. Graphite oxide precursor and ethylene glycol medium were used to synthesize ZnO nanocrystals loaded with graphene nanocomposites by solvothermal steps, and the solvent ethylene glycol in the reaction system was the same as the original reagent. At high temperature, the precursor of graphene oxide is oxidized, except for its surface amount of oxygen groups, to form zinc oxide-graphene nanocomposites.
