Understanding the Challenge of Ozone in Modern Environments
When people think of ozone, the first image is often the ozone layer high in the stratosphere. There, about 90% of the atmospheric ozone absorbs harmful ultraviolet radiation, shielding life on Earth. However, ozone also exists in the troposphere, closer to ground level, where its effects are far less beneficial. Tropospheric ozone is a strong oxidizing gas, capable of reacting with a wide range of substances. While this property is harnessed in disinfection, sterilization, deodorization, and water treatment, elevated concentrations of ozone can be harmful to human health.
Exposure to ozone irritates mucous membranes of the nasal passages, throat, trachea, and lungs, leading to symptoms such as coughing, headaches, chest tightness, and fatigue. Prolonged inhalation of high ozone concentrations may penetrate deeper into the lungs and cause severe respiratory conditions such as pulmonary edema. These risks highlight the need for reliable methods to remove ozone in both industrial and indoor environments.
Catalyst Technology for Ozone Removal
Catalyst-based methods represent one of the most effective solutions for eliminating ozone from air streams. Unlike physical filters, catalysts actively decompose ozone molecules (O₃) into oxygen (O₂) when ozone-laden air passes over their surface. This reaction occurs efficiently at or even below room temperature, without requiring additional heat or external energy.
By employing structured supports such as honeycomb substrates, catalyst systems resolve the trade-off between catalytic efficiency and pressure drop. This design ensures high ozone decomposition rates while maintaining low airflow resistance. Even in conditions with higher airflow velocity—such as those found in office equipment—coated catalysts deliver long-term stable performance.
Substrate Coating for Enhanced Applications
DEAI CHEM’s Ozone Decomposition Catalyst Powder is engineered for uniform coating onto a variety of substrates, including:
Metallic Substrates – Provide high durability and thermal stability, ideal for industrial exhaust systems and chemical processing applications.
Ceramic Substrates – Offer large surface area and resistance to high temperatures, making them suitable for water treatment and ozone destruct units.
Cellulose Substrates – Lightweight and adaptable, widely applied in office equipment filters and indoor air purification systems.
This flexibility in coating allows the catalyst to integrate seamlessly into different air purification systems, ensuring broad applicability across industries and environments.
Advantages of Substrate-Coated Catalysts
