摘要：

NO in N-2 gas was removed by injecting ammonia radicals, which were externally generated by flowing the NH3 gas diluted with Ar gas through dielectric barrier discharge with a one-cycle sinusoidal-wave power source. The NO reduction for changes in both the applied voltage and the repetition rate was well correlated with the discharge power, which was proportional to the total discharge time per unit time. There was an optimum NH3 concentration in the narrow concentration window for the energy efficiency of NO reduction at a fixed discharge power. The maximum energy efficiency was obtained at small values of the NH3 concentration and the discharge power. The low NH3 concentration effectively increased the energy efficiency by drastically decreasing the discharge-firing voltage. (C) 2001 American Institute of Physics.
