摘要：

The TiO 2/SiO 2 coating particles have been prepared by a sol gel method with Ti(OC 4H 9) 4 and SiO 2 as precursors. The IR results indicate the existence of Si—O—Ti bonds on the catalyst. The crystalline phase of coating thin films(TiO 2) was studied by XRD. The amount of TiO 2 bound to the SiO 2 was determined by spectrophotometry. The TiO 2/SiO 2 can be used repeatedly and shows a higher photocatalytic decomposition rate for dichlorvos than TiO 2.
