Contribution of catalytic performance of CeO₂ in nonthermal plasma chemical reaction

Benzene is a harmful material that must be to be removed from flue gases. In this study, the performance of a surface discharge plasma-catalysis combined reactor for benzene decomposition was studied. Benzene conversion and CO₂ selectivity increased upon loading a CeO₂ catalyst onto the plasma reactor. The conversion and selectivity depended on the surface area of the CeO₂. FTIR studies revealed that byproduct organic compounds are formed on the CeO₂, confirming that benzene oxidation occurs on the CeO₂ catalysts.
