Photocatalytic Degradation Of Organic Pollutants By Zinc Oxide Composite

Photocatalysis has been proved to be a promising approach for the degradation of organic pollutants. Oxide semiconductors have shown their recognition in the area of catalysis. Particularly, oxide semiconductor based composites have shown improved photodegradation of organic pollutants by modification of their electronic and structural properties than their single counterparts. ZnO has an advantage of being non-toxic, costeffective and environmentally friendly to become an efficient photocatalyst that can be utilized for preparing different kinds of composites. This chapter summarizes the recent progress in the fabrication and photocatalytic efficiency of various types of ZnO composites for degradation of organic pollutants.
