Beware of Hidden Ozone Pollution: Why are Ozone Decomposition Catalysts Indispensable?

As public awareness of air quality continues to rise, ozone pollution, this "invisible killer," is gradually coming into the public eye. Many people know that formaldehyde and PM2.5 are harmful, but they may not realize that excessively high concentrations of ozone in the air can also seriously threaten health. So, what exactly are the dangers of ozone? Why do we need to actively decompose it? This article will provide detailed answers.

I. Ozone: A Pollutant Near the Ground, a Protective Umbrella at Higher Levels

First, it's important to clarify a concept: The ozone layer in the stratosphere is Earth's "protective umbrella," absorbing ultraviolet radiation and protecting humans and ecosystems. However, the "ozone pollution" we are discussing refers to ozone near the ground, in the troposphere. It is not directly emitted, but rather a secondary pollutant generated by the photochemical reaction of nitrogen oxides and volatile organic compounds under sunlight. Ozone pollution is often more severe on sunny, hot, and windless days.

Near-ground ozone is a strong oxidant, posing significant harm to humans, animals, plants, and materials. Therefore, more ozone in the air is not necessarily better; on the contrary, it needs to be effectively controlled and even decomposed and removed.

II. Harmful Effects of High-Concentration Ozone on Human Health

The most direct harm of ozone is to the respiratory system. Due to its low solubility, ozone can penetrate deep into the respiratory tract, irritating the alveoli and bronchioles. Exposure to high concentrations of ozone can cause symptoms such as dry throat, cough, chest tightness, and difficulty breathing. The harmful effects of ozone are more pronounced in children, the elderly, and those with underlying conditions such as asthma or bronchitis.

Furthermore, ozone irritates the eyes and mucous membranes, causing tearing, eye discomfort, or skin allergic reactions. Long-term exposure to high concentrations of ozone can also cause chronic lung damage and reduce lung function. For this reason, various indoor air quality standards have set clear control requirements for ozone concentrations.

III. Destructive Effects of Ozone on the Ecological Environment and Everyday Objects

Besides affecting human health, ozone also damages the ecological environment and everyday objects. In agriculture, ozone inhibits plant photosynthesis, leading to yellowing and premature aging of leaves, thus affecting the growth of crops and ornamental plants. In natural ecosystems, high concentrations of ozone reduce vegetation productivity and disrupt the food chain.

In daily life and work environments, ozone's strong oxidizing properties accelerate the aging of many materials. Rubber products harden and crack; textiles fade and lose strength; metal surface coatings may oxidize and peel off; and connectors in electronic devices may experience poor contact due to ozone corrosion. In industrial workshops, laboratories, data centers, and other locations, the long-term presence of residual ozone increases equipment maintenance costs and shortens the lifespan of fixed assets.

IV. Sources of Indoor Ozone Are Often Overlooked

Many people believe that staying at home avoids ozone pollution, but this is not the case. Indoor ozone mainly comes from two sources: one is outdoor ozone infiltrating into the room through doors, windows, and ventilation systems; the other is ozone generated by indoor equipment itself.

Common sources of indoor ozone include: air purifiers using electrostatic dust collection technology, ultraviolet disinfection lamps, ozone sterilizers, printers, copiers, laser printers, and other office equipment. These devices generate a certain amount of ozone during operation through high-voltage discharge or ultraviolet light irradiation. If ventilation is poor, indoor ozone concentrations may accumulate to high levels, turning the "purification equipment" into a source of pollution.

V. Catalytic Decomposition: A Scientific Solution for Ozone Removal

Since ozone is harmful, how can it be effectively removed? Currently, the mainstream solution is catalytic decomposition technology. The core principle of ozone decomposition catalysts is to utilize active components such as transition metal oxides to rapidly adsorb and decompose ozone molecules into oxygen. The catalyst itself is not consumed, thus allowing for long-term stable operation.

Compared to other removal methods, ozone decomposition catalysts have significant advantages:
Operating at Room Temperature:No heating or external energy is required; ozone can be efficiently decomposed at room temperature.

Complete Decomposition: Ozone is completely converted into oxygen without secondary pollution, unlike activated carbon adsorption which can become saturated or release oxygen.

Long Lifespan: In dry, clean environments, the catalyst can be used continuously for thousands of hours.

Safe and Environmentally Friendly: The catalyst material is non-toxic and harmless, and can be treated as general solid waste after disposal.

Depending on the application scenario, ozone decomposition catalysts can be manufactured in various forms such as honeycomb ceramics, metal mesh, granules, or coated filter cotton, flexibly adapting to various working conditions including household air purifiers, office equipment, water treatment exhaust gas treatment, and industrial exhaust gas treatment.
