Perchloroethylene gas-phase degradation over titania-coated transparent monoliths

- Catalyst activity increased with number of TiO2 layers on CAM: >90% PCE degradation.
- Study of PCE concentration, flow rate, humidity and irradiance effect on PCO of PCE.
- No competition observed between PCE and H2O molecules to the surface active sites.
- PCO leads to a 90-98% PCE degradation, depending on the operating conditions used.
- A reaction mechanism was proposed for TiO2-CAM PCO of PCE.
