摘要： The present invention provides a catalyst for combustion treatment of suspended particulate matter in diesel exhaust gases, and a combustion catalyst for treating diesel exhaust gases in which a precious metal or an oxide thereof as the catalytic component is loaded on a carrier composed of oxide ceramic particles comprising ceria-zirconia or ceria-praseodymium oxide. In the present invention, depending on the carried precious metal, the carrier is preferably composed of oxide ceramic particles further comprising yttria or lanthanum oxide. The present invention provides a sufficient activity to combust suspended particulate matter in exhaust gases, and can cause combustion at a low temperature of about 300° C. It operates stably for a long period, and can burn suspended particulate matter, especially carbon microparticles.

摘要： The present invention relates to an exhaust gas cleaning catalyst, and aiming at providing a catalyst which has a higher catalytic activity than that of conventional catalysts and, in particular, a strong ability to oxidize nitrogen monoxide. The present invention relates to an exhaust gas cleaning catalyst whose catalytic component is supported on a carrier, characterized in that the catalytic component is platinum colloid which has an average particle size of 80 nm to 120 nm, a particle size D20, a 20% cumulative particle size distribution from smaller particle size side, of 50 nm or more, and a particle size D90, a 90% cumulative particle size distribution from smaller particle size side, of 200 nm or less. The exhaust gas cleaning catalyst of the present invention has a high catalytic activity for cleaning exhaust gases and, in particular, a strong ability to oxidize nitrogen monoxide.
