On the performance and mechanisms of toluene removal by FeOx/SBA-15-assisted non-thermal plasma at atmospheric pressure and room temperature

Enhancement of the non-thermal plasma-catalytic system with different zeolites for toluene removal

“…As shown in Fig.3b the particle size of metallic silver granules on the surface of Ag/HY was about 20nm. Moreover, in the plasma combined catalysis system, the effect of ozone, adsorption/desorption and the direct interaction of gas phase radicals with catalyst surface was also related to toluene removal 10,11,29 . Moreover, Baek suggested that the metals which possessed empty s-orbits and available electrons in the d-orbits could form strong π-complexation bonding 23 , and the πcomplexation adsorption with toluene on Ag also contributed to the enhancement of adsorption abilities of Ag/HY catalyst.…”

In situ FT-IR study and evaluation of toluene abatement in different plasma catalytic systems over metal oxides loaded γ-Al2O3

“…Unfortunately, the NTP technology also leads to harmful by-product (such as NOx, CO and ozone) formation and low carbon dioxide selectivity [4][5]. Recently, NTP combining with heterogeneous catalysis oxidation has been developed, which can eliminate toxic pollutants, reduce the formation of undesirable by-products and improve the carbon dioxide selectivity at ambient temperature [6][7][8][9].…”

Plasma-catalysis of metal loaded SBA-15 for toluene removal: Comparison of continuously introduced and adsorption-discharge plasma system

“…In recent years, SBA-15 and its modified have attracted more and more attention as a promising material in chemical engineering and environmental science because of the large surface area, large pore size and high stability [29,30]. Herein, in this work, a series of Ag, Mn and AgMn loaded SBA-15 samples were prepared using an impregnation method and both their adsorption capacity and catalytic performances were evaluated.…”
