The catalytic ability of prepared catalysts was analyzed by characterizations of XRD, SEM, XPS, and BET. The effects of the SIE and initial concentration on toluene and CO<sub>2</sub> production were discussed in this work. The results showed that the toluene removal efficiency and CO<sub>2</sub> selectivity increased with the promotion of SIE. With the addition of 15% Ce1Mn1/A<sub>2</sub>O<sub>3</sub>, the PPC system displayed the potential performance in the enhancement of toluene conversion and CO<sub>2</sub> generation, and suppression of ozone and NO<sub>2</sub> compared with plasma alone. At the SIE level of 504 J/L, the system showed better performance in terms of toluene removal efficiency (90.1%), CO<sub>2</sub> selectivity (67.3%), O<sub>3</sub> suppression (79.3%), and NO<sub>2</sub> prohibition (61.8%). Also, the organic by-products generated by the PPC system were discussed.</p>
