▎ 摘　　要

The ZnO nanorods/reduced graphene oxide nanocomposites were prepared by using the graphene oxide sheets, zinc acetate, and hexamethylenetetramine as precursors through a facile and green hydrothermal reaction process of 200 degrees C. In the resulting nanocomposites, the graphene oxide sheets were reduced to the reduced graphene oxide sheets, and the ZnO nanorods with a diameter of 100-200 nm and a length of 1-2 mu m were in-situ formed and uniformly distributed over the surfaces of the reduced graphene oxide sheets, which can effectively prevent the reduced graphene oxide sheets from the pi -pi stacking. Interestingly, as photocatalysts, the resulting nanocomposites exhibited significantly enhanced photocatalytic activity on methylene blue under UV illumination, due to the synergetic effects of well dispersed ZnO nanorods and no stack reduced graphene oxide sheets bonded among the ZnO nanorods.
