Application of catalyst in automobile three-way catalytic converter

In the automobile three-way catalytic converter, the main role of the catalyst inner core is to convert CO (carbon monoxide), HC (hydrocarbons) and NOx (nitrogen oxides) in the automobile exhaust into harmless carbon dioxide, water and nitrogen. The specific process is as follows:

‌CO‌ is oxidized to colorless non-toxic carbon dioxide gas at high temperature.

‌HC‌ compounds are oxidized to water and carbon dioxide at high temperatures.

‌NOx‌ is reduced to nitrogen and oxygen ‌.

Through these chemical reactions, the three-way catalytic converter effectively reduces the emission of harmful substances in the automobile exhaust and protects the environment.
