摘要：

The degradation of benzamide and acetic acid with different TiO2 photocatalysts have been studied. These two pollutants differ from each other in their interaction with TiO2 (acetic acid is partially adsorbed on TiO2 whereas and benzamide is not). The results show that the degradation rate of benzamide, contrary to that of acetic acid, is not much affected by the specific area of the catalyst. (C) 2000 Published by Elsevier Science S.A.
