Abstract
An exhaust gas-purifying catalyst includes a substrate, and a catalytic layer supported by the substrate. The catalytic layer includes a support made of alumina, an oxygen storage material, an alkaline earth metal and/or a compound of alkaline-earth metal selectively supported by a surface of the support and dispersed on the surface of the support, and a precious metal supported by the surface of the support. A ratio of a number of moles of the alkaline-earth metal in the catalytic layer with respect to a volumetric capacity of the exhaust gas-purifying catalyst falls within a range of 0.0004 mol/L to 0.35 mol/L.
