Abstract
This study measured the photocatalytic activities of five $TiO_2$ samples commercially available in terms of the degradation rate of nine organic substrates. Efforts were made to correlate the activities with the properties of both catalysts and substrates but little correlation was found. The result clearly shows that the photocatalytic activities sensitively depend on the kind of the test substrates, which strongly supports the fact that the activity measured with one or two model compounds cannot represent the overall performance of a photocatalyst. Therefore, this multi-aspect and inconsistent activity of photocatalytic reaction should be fully understood prior to establish the standard protocol for the activity determination.
