Photo catalytic activity of nanocrystalline TiO2-based films produced by Evades method

Nanocrystalline TiO2-based films have been deposited using a novel and cost-effective Electrostatic Spray Assisted Vapour Deposition (Evades) method for photo catalysis applications. The deposited films mainly have anatase phase with very small amounts of rutile or breakout. This paper reports the photo catalytic activity of the nano structured TiO2-based films under solar light irradiation. The influence of Peg additive and Fe doping on the film photo catalytic efficiency will be presented, as well as the structural changes with the additive and dopant. The results demonstrate that Evades process can produce nanocrystalline anatase films with good photo catalytic activity, and further enhancement of photo catalytic efficiency can be achieved by introducing appropriate Fe doping
