摘要：

All species that are likely to be responsible for nitrogen oxides (N2O, NO, and NO2) conversion in nitrogen plasma are analyzed in detail through carefully designed systematic experiments and theoretical analysis. The effect of ppm-level CO2, CO, and 1% CO on N2O conversion reveals that the N2O conversion occurs mainly by interaction with N-2(A(3)Sigma(u)(+)) excited species. The effect of 1% CO on the NO conversion suggests that only N atom radicals are predominantly involved in NO conversion. NO2 conversion, on the other hand, occurs by interaction with both N-2(A(3)Sigma(u)(+)) and N atom radicals. Therefore, only two active species, N-2(A(3)Sigma(u)(+)) and N atom radicals, are found to be responsible for nitrogen oxides conversion in nitrogen plasma.
