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

Abstract:

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.
