<P>PROBLEM TO BE SOLVED: To produce an exhaust gas cleaning catalyst which is prevented from sintering a catalyst metal; and to provide an exhaust gas cleaning apparatus using the same. <P>SOLUTION: The exhaust gas cleaning catalyst comprises a substrate, a catalyst carrier layer formed on the substrate, and a catalyst metal carried on the catalyst carrier layer; the catalyst metal has ferromagnetism, and the catalyst carrier layer contains ferromagnetic particles dispersed therein. The exhaust gas cleaning apparatus uses the catalyst and is equipped with a detection means for exhaust gas temperatures and a means for controlling the exhaust gas temperatures to a temperature lower than the Curie point of the ferromagnetic particles. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
