Opis

Environmental problem caused by toxic organic pollutants from the domestic and industrial output is now the subject of considerable concern from environmental remediation point of view. In the past decades, great efforts have been made using widely called "Advanced Oxidation Technologies (AOTs)" for treatment of these recalcitrant pollutants to more biodegradable compounds or their mineralization into CO2 and other inorganics. It has been estimated that the amount of solar energy reaching on the Earth every day is more than that mankind could use for three decades. In whole energy of incoming solar spectrum, ultraviolet radiation (400 nm) accounts to only less that 4%. Hence, effective utilization of the visible light of solar radiation, is a long dream of any photochemist. The most important aspect of photocatalysis is a focus probably on metal oxide semiconductor for degradation of organic pollutants in water at ambient conditions using inexpensive and clean solar light and hole as the energy source and oxidant, respectively. The main advantage of this method is that almost all organic pollutants can be mineralized completely into CO2, H2O and inorganic ions.
