To manufacture a catalyst for purifying the exhaust gases from internal combustion engines, which catalyst comprises a skeleton comprising sintered alumina and at least one stabilizing rare earth element oxide and is preferably provided as a coating on a metallic, mineral or ceramic support, and which catalyst comprises at least one noble metal, which is finely dispersed on said skeleton, a solution is provided, which contains at least one noble metal salt and at least one salt of at least one rare earth element and optionally also an aluminum salt. Said solution is subjected to spray pyrolysis in contact with oxygen to produce a composite powder consisting of at least one noble metal, at least one rare earth element oxide and, if desired, alumina. Said composite powder is applied and sintered to a surface layer of the alumina skeleton.
