Plasma-Catalytic Oxidation of Toluene on MnxOy at Atmospheric Pressure and Room Temperature

Fundamental Properties and Applications of Dielectric Barrier Discharges in Plasma‐Catalytic Processes at Atmospheric Pressure

“…The properties of the surface of the catalyst play a crucial role in the plasma-catalytic oxidation of VOCs, because the applied plasma may change the surface, and the presence of the surface changes the discharge properties. Lu et al [86] reported the transition of Mn 2 O 3 to Mn 3 O 4 during the plasma-catalytic oxidation of toluene at ambient temperature, which not only improved the oxidation potential, but also the CO 2 selectivity. Each of the manganese oxidation states was crucial for the oxidation.…”

Low temperature removal of toluene over Ag/CeO2/Al2O3 nanocatalyst in an atmospheric plasma catalytic system

“…To date, great effort has been devoted to the abatement of toluene using the plasma catalytic approach, and it has been demonstrated that the catalysts play a critical role in determining the efficiency of toluene removal in PCS. Ye et al combined dielectric barrier discharge (DBD) with Mn x O y /SBA‐15 catalyst to remove toluene at room temperature and found that toluene removal efficiency is mainly dependent on manganese oxidation states of the catalyst. Wu et al reported that NiO catalyst exhibited the best performance in toluene removal among various metal oxide catalysts due to its high excited oxygen species concentration during the plasma catalytic process.…”

Enhanced plasma-catalytic decomposition of toluene over Co–Ce binary metal oxide catalysts with high energy efficiency

“…The toluene decomposition process in IPC system can be identied into two parts: 12,18 the gas-phase plasma reactions and the catalytic reactions on catalyst surface. According to GC- MS analysis, the reaction pathways of toluene degradation in gas phase are presented (Fig.…”

“…6,7 Catalysts are identied to play an important role in further advancing the plasma-catalytic performance and energy efficiency of IPC system. 8 Heterogeneous catalysts have been employed for VOC decomposition, e.g., noble metals, 9,10 metal oxides, [11][12][13][14] and their combinations. [15][16][17][18][19][20][21] Among these catalysts, metal oxide catalysts (e.g., CoO x , 11 MnO x , 12 CuO 13 and CeO 2 14 ) attract tremendous interest in consideration of the high catalytic activity, good economics and superior poisoning resistance.…”
