Abstract

The traditional application of titanium dioxide was as a white pigment; later, it was discovered their photocatalytic properties as an anode for the photo-oxidation of water. Furthermore, titanium dioxide films are now widely used in catalysis and photocatalysis because of low cost and other advantageous properties. For example, they have been used for decomposition of organic contaminants in air and water. Moreover, recent studies have reported bactericidal and detoxification effects of TiO2 thin films . It has been shown that TiO2- coated materials possess deodorizing, antibacterial, and self-cleaning functions under weak ultraviolet light. Titanium dioxide films can be prepared by many deposition techniques. One of them is the spray pyrolysis (SP) technique which is a low cost, simple to manipulate, and applicable to large-scale areas (final). Photocatalytic TiO2-covered tubing can be used to decompose organic contaminants and/or to sterilize microbial cells in air or water flows , using solar panel reactors or indoor panels irradiated with UV radiation.
