Using cerium oxides as catalysts for the abatement of trichloroethylene by plasma-catalysis route

In this study, the abatement of trichloroethylene was examined with a negative DC corona/glow discharge with CeO2 catalyst downstream. The abatement with the plasma alone system showed a poor COx selectivity. However, by combining the plasma source with CeO2 catalyst the COx selectivity was greatly improved, proving that this plasma-catalysis route shows great potential as air pollution control technology for low concentrated VOC air streams.
