Photocatalytic Oxidation Removal of Gaseous Benzene over TiO2 /ACF Composite Photocatalyst Prepared by Screen-Printed Technology
The TiO2 /ACF composite photocatalyst was prepared by using the screen printed technology. X-ray diffraction (XRD) and scanning electron microscopy ( SEM) were used to characterize the obtained composite. The results of XRD show the TiO2 /ACF composite photocatalyst is confirmed anatase as the only phase present and ACF has no effects on the phase structures of TiO2. The results of SEM show that TiO2 can form thin film on ACF surface. Benzene was chosen as the model of the volatile organic compounds (VOCs) to investigate the capability of TiO2/ACF composite photocatalyst. The results show the TiO2/ACF composite photocatalyst have higher activity for benzene removal than only TiO2 photocatalyst.
