▎ 摘  要

Based on the dispersion effect of chitosan on graphene and chelation effect of chitosan on Co ions, a hydrothermal method was used for graphene/Co3O4 nanocomposites. Ball milling was used for graphene which avoided the properties decrease. In-situ hydrothermal method was used which induced fine dispersion of graphene and Co3O4. XRD results indicate that graphene/Co3O4 nanocomposites are obtained. The hydrothermal temperature has a significant effect on morphologies of precursor. With the temperature increasing, the precursor changes from aggregation to particles. Graphene/Co3O4 nanocomposites are obtained after heat treatment of precursor. Co3O4 distributes uniformly on graphene nanosheets.
