Description

The NO2 decomposition by electron beam irradiation was studied in the NO2-N2 and NO2-rare gas mixtures. The NO2 decomposition yields, G(-NO2), at low doses in the case of the 500 ppm NO2 initial concentration were 2.9, 10.4 and 5.9 for the NO2-N2, NO2-He and NO2-Ar mixtures respectively. A large amount of NO was formed by irradiation of these mixtures. The G(NO) was almost equal to the G(-NO2). The N2O was also formed in the NO2-N2 mixture. The NO2 decomposition is mainly attributable to the attack of N, formed by the radiolysis of N2, on NO2 in the NO2-N2 mixture, and to the attacks of R+ and R*, formed by the radiolysis of a rare gas (R), on NO2 in the NO2-rare gas mixture. The NO2 decomposition in the NO2-N2 mixture was depressed markedly by the addition of a small amount of O2. This may be mainly attributable to the regeneration of NO2 by the reaction of NO with O.
