Titanium-Containing Composite Sorbent-Photocatalyst Based on Calcium Silicates and Aluminosilicates

Abstract

It has been established that the semiconducting properties and the hydraulic activity of the silicates and aluminosilicates of calcium and titanium-containing solid solutions based on them cause simultaneous manifestation of their sorption and photocatalytic properties with mutually reinforcing effect. It is shown that a sharp increase in the rate of degradation of the indicator under the impact of ultraviolet radiation is due not only to its activating function, but also to secondary redox centers being generated in the aquatic environment and to the participation of charged point defects (electrons and holes).
