Fundamental characteristics of N_2O decomposition and formation by atmospheric non-equilibrium plasma were investigated under room temperature without catalysts. A pulsed dielectric barrier discharge (DBD) with a one-cycle sinusoidal-wave power source was employed. In N_2O-N_2 system, an N_2O concentration of 40 ppm was completely decomposed at an applied voltage of 18 kV. In N_2O-O_2-N_2 system, N_2O was produced by elemental reaction in the DBD reactor by contribution of O and N radicals. O_2 concentration was determined to decompose 40 ppm N_2O by the DBD reactor.
