Ozone is widely used across industrial disinfection, air purification, and water treatment processes due to its strong oxidizing properties. However, the same reactivity that makes ozone effective as a treatment agent also makes it a potential hazard when present in uncontrolled concentrations. Accumulated ozone in confined spaces, ventilation systems, or exhaust streams can pose immediate and long-term health risks, particularly to the respiratory system.
To address these challenges, DEAI CHEM’s Ozone Decomposition Catalyst is engineered to convert harmful ozone (O₃) into harmless oxygen (O₂) with high efficiency, long operational stability, and no energy consumption. It provides a dependable method to maintain ozone levels within safe limits in diverse working environments.
1. Why Ozone Must Be Controlled
Ozone exists naturally in the atmosphere, but its effects depend heavily on where it is located:
1）Stratospheric ozone (10–50 km altitude) forms the ozone layer and protects life by absorbing ultraviolet radiation.
2）Tropospheric ozone (surface to ~15 km), however, is a pollutant and can be harmful to human health.
Excess ozone may irritate and oxidize mucous membranes in the nose, throat, and lungs, leading to:
1） Coughing and throat discomfort
2） Headaches and fatigue
3） Chest tightness
4） In severe cases, lung injury or pulmonary edema
Ensuring that ozone is effectively removed from working environments is essential for protecting personnel and maintaining regulatory compliance.
2. Catalytic Mechanism of Ozone Decomposition
DEAI CHEM’s catalyst utilizes a robust metal oxide formulation that enables ozone to break down efficiently at temperatures below ambient conditions. The reaction follows a two-step catalytic pathway:
Step 1:
O₃ + M → MO + O₂
Step 2:
MO + O₃ → M + 2O₂
Where M represents the active catalytic site.
The final product is oxygen, and no secondary contaminants are generated, meeting modern environmental and safety requirements.
3. Key Performance Characteristics
The Ozone Decomposition Catalyst has been optimized to support demanding industrial operations with consistent long-term performance:
1）Effective at low temperatures, suitable for systems operating under ambient conditions
2）Long-lasting stability, with resistance to structural degradation and catalytic poisoning
3）Granular design that ensures uniform gas distribution and low pressure drop
4）Environmentally clean reaction, producing only oxygen and no secondary pollutants
These properties allow the catalyst to operate reliably in continuous and intermittent service environments.
4. Application Areas
The catalyst can be integrated into a wide range of ozone-producing systems and exhaust treatment units, including:
1） Ozone generator off-gas treatment
2） Laboratory and cleanroom ventilation systems
3） Industrial air purification equipment
4） Disinfection and sterilization systems
5） Ozone aging test chambers
6） Water treatment facilities
7） Pharmaceutical, electronics, and semiconductor manufacturing exhaust control
In each application, efficiently removing residual ozone is critical to ensuring personnel safety and maintaining equipment integrity.
5. Operational Considerations
To maintain optimal catalyst performance, the following guidelines are recommended:
1）Ensure adequate airflow and prevent condensation, which may inhibit catalytic activity.
2）Keep the system free of dust and oil, avoiding surface blockage of the catalyst granules.
3）Conduct regular inspections to monitor airflow distribution and pressure drop across the catalyst bed.
4）Refer to the latest SDS from DEAI CHEM for detailed handling, compatibility, and storage requirements.
