Abstract

Abstract:

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.

Key words: plasma, catalyst, NO _x, band gap
