Abstract :

Organic compounds from industries are one of the major causes of water pollution. Various strategies have been employed to remove these toxic compounds. One of the most interesting approaches is heterogeneous photocatalysis because the process is based on the use of solar energy, which is clean and abundant in nature. In this presentation synthesis and characterization of photocatalysts based on semiconducting metal oxides composites are presented. Synthetic techniques are hydrothermal, sonochemical, precipitation and sol-gel methods. Semiconducting metal oxides composites of interest include BiVO4/TiO2 composite; core-shell Fe3O4/SiO2/CeO2 composite, CeO2/SiO2 composite and GO/CeO2 composite. Photodegradation of dyes using the nanocomposites are discussed in terms of kinetics studies.
