(57) [Abstract] [Purpose] N in exhaust gas due to low temperature plasma under atmospheric pressure O X and the particulate stabilizing and effectively reduced. A substrate layer 1 made of a highly electrically conductive material, an electronic insulating layer 2 made of a ceramic material, and an electrode 3 made of a heat resistant highly electrically conductive material are laminated, and the substrate layer and the electrode are formed. An AC power supply 5 is connected between them to excite residual oxygen in the exhaust gas by low-temperature plasma under atmospheric pressure, and CO 2 is formed by the reaction between the excited species and the particulates and NO X is decomposed by the excited species. |
