Abstract:
     The present invention discloses a catalyst for purifying exhaust of motor vehicle. Said catalyst is characterized by using iolite honeycomb ceramic as carrier, using noble metals of platinum, palladium and rhodium containing rare earth elements as active component coating and possessing rare-earth oxide-alumina composite coating so as to obtain effective exhaust-cleaning performance. Said invented catalyst possesses high rare earth oxide content and lower noble metal content, so that it is low in cost, long in service life, quick in cold starting, and can meet the requirements for people's practical application.
