摘要：

This paper is concerned with the study of MOCVD anatase film growth with the aim of assessing the link between the TiO2 surface morphology and the photocatalytic properties of the films, in particular related to the decomposition of organic contamination in the atmosphere. We have found a relationship between the structural properties of TiO2 films deposited by MOCVD at 400 degrees C for differing deposition times, and the corresponding photocatalytic activity which resulted to be different several times depending on the film thickness. The photocatalytic activity measurements were carried out using ethylbenzene at 50 mu g m(-3) in humidified air.
