In non-equilibrium plasma produced by dielectric barrier discharge, removal of CO from automobile exhaust has been studied. Effects of electrical discharge voltage, CO initial concentration, gas flow rate as well as the contents of O 2 and H 2O on the conversion of CO were investigated, respectively. Experimental results showed that CO was mostly converted to CO 2 under dielectric barrier discharge plasma. The conversion of CO was increased with increasing electrical discharge voltage. Moreover, the increasing of CO initial concentration and gas flow rate, the conversion of CO was decreased. After adding to O 2 and H 2O, the conversion of CO was obviously promoted. In addition, mechanism of CO conversion under dielectric barrier discharge plasma was discussed.
