Description

Three-way catalysts containing precious metals such as platinum are used for purification of exhaust gas from gasoline-fueled automobiles, but because of rising demand and soaring prices for precious metals, it is necessary to develop alternative catalysts with comparable properties. This study examined the synthesis of an electrical heating alumite plate catalyst containing cerium, iron, and carbon and its properties in exhaust purification. The catalyst was synthesized by impregnation using an organometallic solution of cerium tartrate and iron ammonium citrate and by vapor-phase treatment with carbon monoxide. The electrically heated alumite plate catalyst containing cerium, iron and carbon was found to have excellent properties for purification of automobile exhaust gas.
