Photocatalytic degradation of chlorinated ethenes
Degradation of three chlorinated ethenes, trichloroethylene, trans-1,2-dichloroethylene and cis-1,2-dichloroethylene, by UV-light irradiated TiO2 catalyst prepared by the sol-gel method in dry air at ambient temperature have been examined by using FTIR measurement. The chlorinated ethenes rapidly de...

| description | Degradation of three chlorinated ethenes, trichloroethylene, trans-1,2-dichloroethylene and cis-1,2-dichloroethylene, by UV-light irradiated TiO2 catalyst prepared by the sol-gel method in dry air at ambient
temperature have been examined by using FTIR measurement. The chlorinated ethenes rapidly decomposed
to produce dichloroacethyl chloride, CO, HCl, and COCL2. For trans- and cis-1,2-DCE systems isomerization
to each other is found to be the first step of the degradation. The C = C bond of the chlorinated ethenes
interacts directly with TiO2 site and, consequently, the degradation results in several products on the catalyst
surface in these systems. |
