Automobile exhaust three-way catalyst is made up of highly stable perovskite materials, rare earth and trace oxygen storage material of precious metals (Pt, Pd, Rh) composite, through the special load to the preparation of ceramic honeycomb carrier surface coating technology. It has completely transformed with low temperature (active high), good heat resistance, long service life, etc. Automobile exhaust catalyst can effectively eliminate CO, HC and NOx pests, such as catalytic performance reach the Ⅲ standards.
