吸附剂负载TiO2光催化研究进展

iO2 photocatalysis has exhibited attractive perspective in various applications of environmental protection field, especially for wastewater treatment and air purification. It is necessary to immobilize the nanosized titania onto supports for its application. Composite photocatalyst realized by loaded TiO2 onto porous adsorbent exhibited high activity and better separation performance due to the high pollutant concentration and better TiO2 dispersion. In this paper, the recent progress of preparation and photocatalytic properties of TiO2/adsorbent composite photocatalyst was reviewed. Furthermore, immobilization methods, types of porous adsorbent and mechanism of adsorbent for the enhanced photocatalytic activity were emphasized.
