Abstract: Provided is an exhaust gas purifying catalyst with an excellent effect of suppressing deterioration due to aggregation of a noble metal catalyst that would occur during endurance at a high temperature. The exhaust gas purifying catalyst includes a porous support and a noble metal catalyst carried on the porous support. The porous support contains particles of an alumina-ceria-zirconia composite oxide, and the porous support has the following physical property values after subjected to baking at 900° C. for 5 hours: a pore diameter of the particles in the range of 2 to 20 nm, a specific surface area of the particles in the range of 75 to 115 m2/g, a crystallite size of a ceria-zirconia composite oxide that is contained in the particles in the range of 4 to 6 nm, and a bulk density of the particles in the range of 0.5 to 0.9 cm3/g.

Abstract: A manufacturing method of steel in which an element of the treatment gas is dissolved and diffused includes heating the steel, making a treatment gas contact a surface of the steel such that an element of the treatment gas dissolves and diffuses from the surface of the steel into a surface layer thereof, and reducing a concentration of the treatment gas near a non-treatment surface that is a portion of the surface of the steel.
