Three-way catalysis refers to the catalytic action of converting harmful gases such as CO, HC and nitrogen oxides in automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. Three-way catalytic converter is mainly used. The carrier part of the three-way catalytic converter is porous ceramic material, which is installed in a special exhaust pipe. It is called a carrier because it does not participate in the catalytic reaction itself, but is covered by a layer of precious metals and rare earths such as platinum, rhodium and palladium. It is the most important external purification device installed in the automobile exhaust system.
