Degradation of Organic Pollutants by Titanium Dioxide Matrix Composites

Abstract

As a semiconductor material, titanium dioxide has the advantages of stable chemical properties, no pollution and low price, which is widely used in the field of organic pollutant degradation. The modification methods of semiconductor composite and nonmetallic doping for titanium dioxide are described. The degradation efficiency of modified titanium dioxide composite for organic pollutants is proposed. The advantages and disadvantages of the composite in preparation and application are pointed out. Finally, the development direction of modified titanium dioxide composite in the future is described.
