Why is oxygen safe but ozone is not? Is there any way to eliminate ozone?
Compared with oxygen, ozone is unstable and even more reactive than oxygen. From a thermodynamic point of view, ozone is more unstable than oxygen because the decomposition of ozone into oxygen releases heat and increases entropy. These two effects reinforce each other, resulting in huge negative energy changes. Ozone is highly oxidizing and has a strong bactericidal effect. Studies have shown that ozone can kill more than 99% of the propagules within 5 minutes. At the same time, ozone also serves the purpose of deodorization. Many indoor air purifiers use the strong oxidizing property of ozone as a principle to oxidize organic matter in the air to purify the air.
Ozone reacts with living tissues. In plants, ozone hinders photosynthesis and reduces crop yields. In the human body, ozone can inflame the fragile tissues of the lungs, making them prone to asthma and infection. Inhaling excessive ozone can directly irritate the nasal cavity, throat and trachea, causing symptoms such as coughing, chest tightness, and sore throat. In particular, asthma patients or people with respiratory diseases react more violently, which may cause acute attacks of these diseases. People who are in a high-concentration ozone environment for a short period of time will suffer from headaches, dizziness, decreased concentration, and even nausea due to insufficient oxygen supply to the brain.
Therefore, in some scenarios where the ozone concentration exceeds the standard, we will use ozone decomposition catalysts to solve the damage caused by ozone to us. Its main principle is derived from its own reduction reaction. It can accelerate the decomposition of ozone into oxygen. The catalyst adsorbs ozone molecules on the surface, causing chemical bonds to break, generating oxygen and oxygen free radicals, thereby efficiently converting ozone into harmless oxygen.
Ozone decomposition catalysts are widely used in industrial waste gas treatment, air purification, medical equipment and other fields, and have become a powerful assistant in the environmental protection industry!
