Abstract
A method utilizes a three-way catalytic converter, having a catalyst formed from a plurality of particles each including a first metal oxide center, a second metal oxide monolayer, and a catalytically active metal to decrease concentration of hydrocarbons, carbon monoxide, and nitrogen oxides in exhaust gas during stoichiometric, rich, and lean conditions, wherein a molar ratio of metal in the monolayers to metal in the centers is between about 0.01 and 0.2.
