An active perovskite‐type catalyst (La 0.8 K 0.2 Cu 0.05 Mn 0.95 O 3 ) was prepared and characterized using XRD, BET, and SEM. Then, the effect of catalysis on plasma assisted catalytic removal of nitrogen oxides and soot was investigated by combining temperature programmed reaction (TPR) and the analysis of Fourier transform infrared spectroscopy (FT‐IR). When the C 3 H 6 concentration in the feed gas is 0.27 %, the maximum NO x removal rate increases from 43.5 % to 72.2 % after adding catalyst. FT‐IR results indicate that the addition of catalyst will promote the removal of NO x , HC, and soot. There is still great amount of NO x and HC remaining after plasma reaction, little NO x and almost no HC after catalytic reaction, and no NO x and HC after plasma assisted catalytic reaction.
