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 semiconductor – that means composite material. There are several catalysts reported in the literature. Among the metal oxides such as TiO2, ZnO, SnO2, and CeO2, CuO is extensively used in heterogeneous photocatalysis for degradation of organic compounds degradation. Its activity can be enhanced by several L. Favier Univ Rennes, École Nationale Supérieure de Chimie de Rennes, CNRS, ISCR – UMR6226, Rennes, France M.
