Abstract
Photocatalysis belongs to one of the Advanced Oxidation Processes (AOP). These processes make possible the decomposition of organic compounds to carbon dioxide and water. The most useful photocatalyst is titanium dioxide which, to make it active, requires irradiation with suitable wavelengths. Pure titanium dioxide can be activated only by ultraviolet light irradiation (UV). For a long time, studies have been carried on modified titanium dioxide materials to obtain more effective photocatalysts with greater activity under UV light irradiation or to obtain photocatalysts which may be active also under visible light irradiation. One of the possible ways for modifying TiO2 is carbon modification. This type of modification increases the adsorption capacity, and activation of the photocatalysts is then possible under visible light; moreover, the lifetime of the material is longer. What type of carbon-modified material is desired will depend on different preparation techniques so as to control the desired properties of the carbon-modified TiO2.
