Research Progress in Supported TiO₂ Photocatalysts

TiO₂ 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 nano-sized titania onto supports for its application.Porous materials supported TiO₂ photocatalysts have attracted much attention because of their high photocatalytic efficiency and easy recycle.In this paper,the progress of preparation and photocatalytic properties of TiO₂adsorbent composite photocatalyst was reviewed.
