The removal of nitrogen oxides by catalyst and low-temperature plasma is remarkable.Five catalysts with different band gaps，such as WO3，ZnO，NiO，CdS and Cu2O，were prepared.By means of SEM，XRD and Raman characterization，the catalytic oxidation performance of NO and NO x combined with low temperature plasma was compared.P-type semiconductors had no effect on NO x removal，while N-type semiconductors had obvious effect on NO x removal.The order of oxidation efficiency from big to small was CdS，WO3，ZnO，which was exactly opposite to their band gap values.The degradation efficiency of NO and NO x by CdS was 98.4% and 84.4% respectively，and the catalytic performance of CdS recycling was still good.The specific effects of plasma and catalyst on the reaction process and the coupling between them were described.The determination of NO3- and NO2- on the surface of samples catalyzed by discharge by ion chromatography was conducive to further understanding of such synergistic mechanism.
