What is an ozone destruction catalyst?

Ozone destruction catalyst is made of active ingredients manganese dioxide (MnO2) and copper oxide (CuO). It has a black or dark brown appearance and is available in columnar, granular and powdery forms. The catalyst is mainly used to destroy ozone in exhaust emissions and can effectively decompose ozone into oxygen at room temperature without any additional energy.
Ozone destruction catalysts can efficiently decompose ozone into oxygen, eliminate ozone odor, and achieve tail gas emission standards. The catalyst uses chemical synthesis to manufacture active ingredients, accurately controls each process parameter of the synthesis reaction, uses alumina as a binder, and the active ingredient content is as high as 85% or more. The powder does not contain a binder, and the active ingredient content is as high as 99% or more. The catalyst does not contain activated carbon, can withstand high temperatures when treating high-concentration ozone, does not burn, is non-volatile, is safe to use, and does not cause secondary pollution.
It can effectively provide ozone utilization and mineralization capacity for organic matter, greatly saving operating costs, and is an ideal catalyst for the new generation of ozone destruction catalytic oxidation.
Ozone is a secondary pollutant, and before automobile exhaust is discharged, pollutants such as nitrogen oxides (NOₓ) and hydrocarbons (HC) in the exhaust react with sunlight in the atmosphere to generate ozone. Therefore, the core goal of automobile exhaust treatment is to reduce the emission of these "ozone precursors". The goal of ozone destruction catalysts is to remove "ozone precursor pollutants" rather than directly treat ozone. Ozone destruction catalysts can remove pollutants such as nitrogen oxides in exhaust gas, thereby achieving standard exhaust emissions, reducing air pollution, and protecting people from breathing fresh air.

In addition to treating automobile exhaust emissions, ozone destruction catalysts are also used in industrial waste gas, ozone water treatment and other scenarios. Its emergence has made great contributions to environmental protection and the industrial field. With the continuous improvement of science and technology, ozone destruction catalysts will be used in a wider range of scenarios and play a greater role.
