A catalyst for the purification of exhaust gases comprising a catalyst carrier layer and catalyst ingredients carried thereon, is capable of enhancing the purification property by suppressing the growth of cerium oxide particles and preventing the formation of LaAlO.sub.3. This catalyst has two composition types. One is a binary composition catalyst comprising oxides of cerium and zirconium in the catalyst carrier layer and the other is a ternary composition catalyst comprising oxides of cerium, zirconium and lanthanum in the catalyst carrier layer.
