Abstract: Photocatalytic process for many years as one of the world�s environment solutions used in industrialized countries. Nanotechnology is the creation of a new approach in the future photocatalyst huge industry in this area promises. Photocatalytic oxidation processes, pollution caused by ultraviolet radiation in the presence of catalysts such as titanium dioxide or zinc oxide semiconductor completely destroyed and converted to CO2 and H2O are. Photo nanostructured catalysts with high catalytic properties of hydrophilic and power due to their high surface to volume ratio is one of the key technologies in environmental pollution control requirements. The main objective of the project review and evaluate the photocatalytic degradation of pollutants in smoke from fossil fuels during the process of photocatalytic reactions in an air purification system. In this regard, the mechanism of action of the photocatalyst, types and characteristics and application of photocatalytic and the impact of the main operating parameters such as tiny fraction of the mass of pollutants such as CO2, CO, C3H6, H2O, NO2, P, SO2 and dynamic pressure under the photocatalytic reaction was studied. The results photocatalyst and mass fraction pollutants after considerable damage photocatalyst photocatalytic reaction compared to the reaction of pollutants before the show.
