The supported TiO2 photocatalyst has been reported for the photodegradation of different organic pollutants. These supported TiO2 photocatalysts include metal and non metal doped TiO2 photocatalysts. The photodegradation can be explained in terms of adsorption. The adsorption of the dye is an significant and obvious parameter in the photodegradation process. The photodegradation is directly related to the adsorbed quantities of the pollutant onto the surface of adsorbant. Adsorption of Orange II, an azo dye has been reported using different adsorbents like fly ash, activated carbon and porous titanium dioxide. This review presents a comparison of maximum adsorption capacities (Qm; mg.g–1) and Langmuir adsorption constant (Kads; L.mg–1) for the adsorbents reported in previous studies.

AbstractTitanium dioxide-mediated photocatalytic mineralization of two selected organic pollutants such as Metalaxyl (ML) and Tinidazole (TN) has been investigated in aqueous suspensions in the presence of atmospheric oxygen under a variety of conditions. The mineralization was studied by monitoring the depletion in total organic carbon (TOC) content as a function of irradiation time. In addition HPLC analysis technique was also used to monitor the degradation of model compounds under investigations. The mineralization kinetics of both compounds were investigated under different conditions such as type of TiO

Water Cleavage

The breakthrough work of Fujishima and Honda in 1972 [1], in which they achieved ultraviolet light-induced water cleavage with the use of titanium dioxide (TiO2) in an electrochemical cell, has drawn considerable attention in recent years to the “acceleration of a photoreaction by the presence of a catalyst” [2] or photocatalysis. Research on photocatalysis has explored the decomposition of organic pollutants and microorganisms, the superhydrophilic self-cleaning properties of surfaces, and the photosplitting of water, among other applications. Semiconductors can act as photocatalysts because of their electronic structure and TiO2, in particular, has been a popular choice. It is non-toxic and mechanically stable, can be fabricated at low-cost, and the anatase phase of TiO2 has a bandgap of approximately 3.2 eV, ideal for excitation by light in the ultraviolet range.
