Synthetic dyes are poisonous and heavy chemicals that can produce concentrated colors are dangerous to the surroundings. These dyes are opposed to bio-decomposition and have pernicious effect on human health. Adsorption, ultra filtration, extraction, oxidation ozone and hydrogen peroxide are some of the conservative technique utilized to eliminate color from industrial runoff noxious materials [7]. Advanced oxidation processes (AOPs) are substitute to all other techniques, of which the photo-catalysis is the most popular one. In current scenario, heterogeneous photo-catalysis technique can direct to the full deterioration of various inorganic, organic dyes in industrialized operations. There are many semiconductor components are available which acts as photo-catalyst such as TiO2, MnO2, ZnO etc. The system depends on the concept of decaying various organic hazardous substances speedily and not a particular one. Among many photo-catalyst element, TiO2 and ZnO are the best photo-catalyst because they have broad band gap. TiO2 is the extensively favored because it is harmless, steady, biologically static, excellent absorption/desorption properties, safety and photo corrosion stability [8]. A TiO2 photo-catalyst has achieved several significant in the ancient times due to its outstanding quality of degrading the
