As an essential pollution gas,NO gas has drawn attentions for investigating its removal microscopic mechanism,in order to improve the removal efficiency.The fluorescence technique has been applied to analyze the NO removal dynamics with O2 or without O2 using negative pulsed streamer discharge plasma.Results indicate that,without the participation of O2,the direct collision dissociation between energetic electrons and NO molecular have played a major role for NO removal.Such a removal reacting pathway can be presented as NO+e*→NO*+e→N*+O*+e,which produces O and N atoms and then O2 and N2 molecules.With more oxygen,the major removal reaction of NO has been changed to the oxidation reaction to yield NO2 rather than the former reduction reaction.
