摘要：
An exhaust gas purification catalyst of the present invention contains at least a precious metal coated with lanthanum-containing alumina. In at least one embodiment, it is possible to provide: an exhaust gas purification catalyst which can (i) have an increase in heat resistance, and (ii) inhibit the precious metal from being mixed in alumina and therefore inhibit the precious metal from forming a solid solution in combination with alumina; and a method for efficiently purifying, by use of the catalyst, an exhaust gas emitted from an internal-combustion engine.
