The degradation of benzamide and acetic acid with different TiO2 photocatal
ysts have been studied. These two pollutants differ from each other in thei
r interaction with TiO2 (acetic acid is partially adsorbed on TiO2 whereas
and benzamide is not). The results show that the degradation rate of benzam
ide, 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.
