Study on the performance and mechanism of degradation of toluene with non-thermal plasmas synergized supported TiO2/γ-Al2O3 catalyst

Degradation of Benzene Using Dielectric Barrier Discharge Plasma Combined with Transition Metal Oxide Catalyst in Air

“…A large amount of active species are obtained, such as free radicals OH and O, through the frequent collision of electrons and background gas molecules [33]. Besides this, the excess energy would transform into heat in the discharge area, and a lot of reactive particles would emit ultraviolet light, which would cause more O 3 to transform into reactive atomic oxygen species [34]. Thus, the probability of benzene molecules colliding with reactive particles in the DBD discharge region is enhanced, causing an increase in the degradation efficiency.…”

Volatile organic compound removal by post plasma-catalysis over porous TiO2 with enriched oxygen vacancies in a dielectric barrier discharge reactor

“…19,21 The second strategy is the traditional hybrid system, which couples TiO 2 with noble metals or metal oxides, which possess higher catalytic capacity. 22 Thus, a series of TiO 2 -based catalysts have been designed and applied in NTP reactors for VOC purification, such as Ag/ TiO 2 , 23 Au/TiO 2 , 24 Co 3 O 4 /TiO 2 , 25 NiO/TiO 2 , 26 and Cu x O/TiO 2 . 27 However, obtaining the full inherent potential of TiO 2 catalysts in NTP applications remains challenging.…”
