Fabrication of ZnO and TiO2 Combined Activated Carbon Nanocomposite and Adsorption Enhanced Synergetic Photocatalytic Effects

The ZnO-AC/TiO2 compounds performance as,photocatalyst have been investigated. The samples were checked by scanning electron Microscopy, specific surface area X-ray diffraction analysis and energy dispersive X-ray spectroscopy (EDX): The photocatalytic activities Were evaluated by the photocatalytic oxidation of methylene orange solution. It was found that the prepared ZnO-AC/TiO2 composite material having excellent photocatalytic activity under visible light irradiation:. A small amount of ZnO in composites AC/TiO2 significantly increase its photocatalytic activity.
