Evolution of ZnO-Based Photocatalyst for the Degradation of Pollutants

  • S. Kaviya
Chapter
Part of the Environmental Chemistry for a Sustainable World book series (ECSW, volume 36)

Abstract

One exciting aspect of research is focused on the treatment of wastewater and complete mineralization of the pollutants by photocatalysis. The aromatic structure and complex nature of the pollutants cause difficulties in decomposition and complete mineralization. Progress in photocatalytic degradation would be very interesting if it were under moderate reaction conditions with a cost-effective catalyst with enhanced efficiency. Various nanocomposite materials have been used for this purpose. Here, we provide a detailed summary including the latest literature reports on the evolution of the zinc oxide (ZnO) photocatalyst used for the degradation of contaminants from wastewater.

Keywords
