Study on Preparation and Photocatalytic Activity of Nano-TiO2/Precipitated Silica Composite Material

摘要：

　　Using precipitated silica as the carrier, a kind of composite photocatalyst was prepared through hydrolysisde positing method.The obtained composite material was characterized by XRD, SEM, TEM, FT-IR.Based on the experimental results and analysis of characterization, the preparation mechanism of composite powder material was studied.The photocatalytic degration experiment of Rhodamine-B indicates that the precipitated silica is an ideal carrier of the TiO2,and the photocatalyst can combine with the silica tightly.The photocatalytic activity of the obtained composite material is stabilize and constant.
