Abstract

A catalyst which is capable of carrying out simultaneously the oxidation of hydrocarbons and of carbon monoxide and the reduction of nitrogen oxides which are present in the exhaust gases of internal combustion engines comprises a support of inert material coated with lanthanum oxide and a catalytic phase constituted by ruthenium combined with lanthanum in the form of mixed oxide of the perovskite type, by platinum or palladium and by rhodium.
