摘要

The present invention improves the reduction performance of nitrogen oxides compared to the existing three-way catalyst, suppresses the emission of nitrous oxide and ammonia at the same time, and simplifies and applies the process by a method of doping an iridium-ruthenium catalyst to a commercial three-way catalyst later The purpose is to expand the scope. The present invention simultaneously discharges ammonia and nitrous oxide in which an iridium-ruthenium catalyst component is doped into a three way catalyst (TWC), a diesel oxidation catalyst or a lean NOx trap supported on a honeycomb carrier. It provides an inhibitory catalyst.
