摘要：

Photocatalytic degradations of C2HCl3, CHCl2COOH and phenol were studied over twelve commercial TiO2 samples of different crystal forms and crystallinities. The initial degradation rate (r0) was determined principally by the anatase content of the TiO2. r0 per unit surface area of a TiO2 particle increased proportionally with the crystallite size of TiO2. Platinization of TiO2 was more effective on rutile than anatase.
