<p><P>PROBLEM TO BE SOLVED: To provide a catalyst for burning PM (particulate matter), which can be used for continuously burning PM even at comparatively low temperature of exhaust gas from a diesel engine while dispensing with external energy. <P>SOLUTION: The method for manufacturing the catalyst for burning PM comprises the steps of: dispersing a Ce oxide particle in an aqueous solution; dissolving water-soluble Ag salt in the Ce oxide particle-dispersed aqueous solution; adding diethanolamine to the resulting aqueous solution; irradiating the diethanolamine-added aqueous solution with ultrasonic waves to reduce and precipitate the Ag fine particle on the surface of the Ce oxide particle. According to this manufacturing method, the catalyst having the Ag fine particles deposited uniformly on the surface of the Ce oxide particle can be manufactured. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
