Abstract

PURPOSE:To clean the exhaust gas with a high efficiency by using a ternary element catalyst prepared by supporting lanthanum oxide, platinum, and/or palladium on a ceramic porous support. CONSTITUTION:As the celaning catalyst for exhaust gas discharged from an internal-combustion engine, etc., is prepared by supporting lanthunum oxide, platinum, and palladium on a ceramic porous support. The catalyst is capable of cleaning noxious components such as NOx, CO, and hydrocarbons present in exhaust gas concurrently and with high efficiency and also can be manufactured at low cost.
