(57) [Summary] (Modified) [Purpose] It is possible to improve the NOx purification performance in a lean atmosphere, which was not active with conventional catalysts. An exhaust gas purifying catalyst capable of purifying NOx and a method for manufacturing the same are provided. [Structure] The following general formula: Cu a Co b Al d O g (where a, b and d represent the atomic ratio of each element, and d = When 2.0, a = 0.01 to 0.3, b = 0.05 to 0.4, and g is the number of oxygen atoms required to satisfy the valences of the above components.), A multi-component complex oxide containing copper, cobalt and aluminum. To do. |
