    Abstract: A catalyst, which has high and long-lasting activity on both the oxidation of hydrocarbons and carbon monoxide and the reduction of nitrogen oxides particularly when an internal combustion engine is operated at an air-fuel ratio around a stoichiometric ratio, consists of a carrier of active alumina, 0.05-0.2 Wt% platinum, 0.0015-0.045 Wt% rhodium and 0.002-5 Wt% boron.
