A novel Mn-Ce-Nb-Ox/P84 catalytic filter for synergetic removal of particulates and NO was designed and prepared by a new method using functional foaming coating. Removal characteristics of nitrogen oxides (including catalyst loading amount, O2 concentration, NH3/NO molar ratio, H2O and SO2) and particulates, were systematically studied. Results showed that the NO removal efficiency of catalytic filter reached 95.3% at 200 °C, as the catalyst loading amount, filtration velocity and mole ratio of NH3/NO were set to be 450 g/m2, 1 m/min and 1, respectively. The removal characteristic of particulates of Mn-Ce-Nb-Ox/P84 catalytic filter belonged surface filtration and the PM2.5 removal efficiency reached 99.98%.
