TiO2/Fly Ash Nanocomposite for Photodegradation of Organic Pollutant

Abstract

Photocatalytic materials are currently intensively studied because of their high potential in UV and solar-light water purification. The photocatalysis is based on charge carrier generation and mobility of electron/hole pairs. Usually, a large amount of photoexcited charge it is lost by recombination, there are necessary coupled materials, highly active photocatalysts, and a very good electron acceptor semiconductorthat means composite material. There are several catalysts reported in the literature. Among the metal oxides such as TiO 2 , ZnO, SnO 2, and CeO 2 , CuO is extensively used in heterogeneous photocatalysis for degradation of organic compounds degradation. Its activity can be enhanced by several

“…As a photocatalyst, metal oxide nanoparticles have shown remarkable effectiveness in mineralizing various environmental contaminants, including detergents, dyes, and volatile organic compounds [102]. Various metal oxides, such as Ag 2 O, TiO 2 , ZnO, WO 3 , Fe 2 O 3 , and CuO, have recently been used as essential photocatalysts for degrading organic dye pollutants in water and air [103].…”
