| Research Abstract |
Volatile chlorinated organic compounds (VCOCs) have been serious environmental problems because they are toxic and carcinogenic to animals. Titanium dioxide photocatalysts have been good candidates as the remediation technique for the degradation of VCOCs. However, the photocatalytic activity decreases during the photocatalytic degradation of gaseous chlorinated ethanes. This study has clarified the degradation mechanism of the chlorinated ethanes and the reason for the deactivation of the photocatalysis. Furthermore, we found that in the absence of oxygen in the reactant gas stream, the photocatalytic degradation of chlorinated ethanes formed ethylene and ethylene chloride which are useful alkenes for chemical industries. Conversion to these alkenes from the chlorinated ethanes was studied under various experimental conditions.
