摘要: Characteristics of toluene decomposition and formation nitrogen oxide (NOx) by-products were investigated in a dielectric barrier discharge (DBD) reactor with/without catalyst at room temperature atmospheric pressure. Four kinds metal oxides, i.e., manganese (MnOx), iron (FeOx), cobalt (CoOx) copper (CuO), supported on Al2O3/nickel foam, used as catalysts. It was found that introducing catalysts could improve removal efficiency, promote by-product ozone enhance CO2 selectivity. In addition, NOx suppressed with the decrease specific energy density (SED) increase humidity, gas flow rate concentration, or introduction. Among four catalysts, CuO showed best performance suppression. The MnOx exhibited lowest concentration O3 highest selectivity but NOx. A possible pathway for production DBD discussed. contributions oxygen active species hydroxyl radicals are dominant
