| Abstract: | The TiO2 photo-catalyst loaded on pumice, Al2O3, MST-5A and glass ball was prepared by the dip-coating method. The photocatalytic activities of the prepared catalyst were evaluated by the decolorizing efficiency of active Bright Red X-3B under the condition of micro- wave (MW) combined with ultraviolet (UV) radiation. The results showed that micro- wave enhanced the photocatalytic activity of the catalyst, and the photocatalytic activity of TiO2/pumice was higher than that of the others. The affecting factors, such as pH, H2O2 and life of catalyst in the TiO2/pumice reaction system were also studied. The experimental results showed that TiO2/pumice has the advantages of stable structure, and long photocatalytic life, being suitable to be applied to the industries. |
