Abstract:Cordierite honeycomb catalysts supported on rare earth (RE)-transition metal oxides, used for removing simultaneously three major pollutants, carbon monoxide (CO), hydrocarbon (HC) and nitrogen oxides (NOx), in automotive emission have been investigated. The results indicate that the catalyst has improved three-way performance (TWP).
Keywords:Automobile exhaust  three-way catalyst  adsorption
