Abstract

This paper introduces the preparation of composite photocatalyst TiO2·SiO2attached to the hollow glass microbeads by the dip-coating technique using TiCl4 and tetraethoxysilane as raw materials. The photocatalytic degradation of organophosphorous pesticides is studied. The results show that the photoactivity of TiO2·SiO2 /beads is improved,and the best photocatalyst produces1. 35 times of Degussa P - 25 TiO2. Moreover,the adsorption and the surface area are also introduced in this paper, and the surface condition and particle size of the composite photocatalysts are characterized by TEM and SEM.
