摘要: Abstract The destruction of low concentrations toluene using two non-thermal plasma catalytic systems has been investigated in this study. Metals (Ag, Mn and AgMn) loaded SBA-15 catalysts were prepared by an impregnation method further characterized X-ray diffraction (XRD), N 2 adsorption–desorption isotherm H -temperature-programmed reduction (H -TPR). In our research, types system, including continuously introduced adsorption-discharge studied. results showed that the metals retained highly ordered mesopore structure SBA-15. activities as-prepared for conversion carbon balance both decreased following order: AgMn/SBA-15 > Ag/SBA-15 > Mn/SBA-15 > SBA-15, which consistent with ozone decomposition activities. Compared to traditional system slightly increased significantly improved balance. reaction intermediates products detected GC–MS situ FT-IR analyses. organic byproducts greatly compared system. Moreover, different mechanisms discussed.
