Abstract

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