摘要：

Zinc acetate and expanded graphite were selected as raw material. Under vacuum, the initial reaction solution was infused in the interlayers of expanded graphite. Then, zinc oxide nanorods/graphene composites were prepared by solvothermal method at 180 degrees C for 12 h. The structure and the morphology of products were characterized by X-ray diffraction(XRD) and transmission electron microscopy(TEM). The results show that the zinc oxide nanorods uniformly grow on the surface of graphene sheets. The average diameter of rod-like zinc oxide is about 50 nm, and the length is about 150-200 nm. The zinc oxide nanorods/graphene composites exhibited high photocatalytic activity in the degradation of methylene blue under UV lights in comparison with bare Degussa P25.
