Preparation and Properties of Composite Photocatalyst of Needle ZnO Nanorod Grafted in the Pores of Expanded Graphite

A composite photocatalyst of needle ZnO nanorod grafted in the pores of expanded graphite (EG) was prepared by a process of hydrolysis method directly, in which the expanded graphite was prepared by microwave irradiation. Scanning electron microscope (SEM) and Fourier transformation infrared spectroscope (FT-IR) were used to characterize the structure and the chemical structure of the photocatalyst. The results indicate that expanded graphite had a unique net-like pores structure and ZnO Nanorod was loaded on EG to form EG/ZnO composite photocatalyst.
