The results show that photocatalyst TiO2 improves the removal rate of toluene in not only the nitrogen plasma field (NTP-P-O2/N2) eradiating ultraviolet light but also the argon plasma field eradiating visible light. This supports the idea that both the UV light and the high-energy electron in the plasma field can activate TiO2. Furthermore, the toluene removal rate in NTP-P-Ar system is 5% higher than that in NTP-P-O2/N2 system, confirming that high-energy electron has greater effect on the degradation performance of toluene, as compared with UV light.
