摘要：

Serial novel supported photocatalysts: HPAs/TiO2/SiO2 composite, such as H3PW12O40/TiO2/SiO2, H4SiW12O40/TiO2/SiO2 and H3PMo12O40/TiO2/SiO2, were synthesized via impregnation, respectively. TG-DSC, XRD, FT-IR, SEM and BET characterized the physicochemical structures of products. The photocatalytical performance testing showed that the as-prepared composites have higher catalysis activity than that of parallel TiO2/SiO2 for the degradation of model CBW aqueous.
