摘要：

TiO2 thin films were prepared by spin coating and spray pyrolysis techniques. The observed photocatalytic activity is the same for films prepared by both techniques. The photocatalytic activity increases as film thickness increases but remains constant after the thickness reaches 0.60 mum. These films are shown to be capable of photodecomposing organic impurities in water.
