Application of ozone decomposition catalyst in waste gas treatment

With the increasing awareness of environmental protection, waste gas treatment has become an indispensable part of industrial production. As an efficient waste gas treatment material, ozone decomposition catalyst is gradually emerging in the field of waste gas treatment. It can not only effectively decompose ozone in waste gas, but also convert other harmful pollutants into harmless substances through a series of chemical reactions, providing strong support for improving air quality.
The working principle of ozone decomposition catalyst is based on the active sites on its surface. These active sites are usually composed of metals or metal oxides such as iron, copper, and manganese. They have unique electronic structures and chemical properties, and can efficiently decompose ozone into oxygen at room temperature without additional energy input. When ozone molecules come into contact with the surface of the catalyst, they are adsorbed onto the active sites. Under the specific chemical environment created by the active sites, the chemical bonds of the ozone molecules become unstable, resulting in decomposition reactions to generate oxygen molecules and active oxygen species. Among them, the active oxygen species are further converted into highly oxidizing hydroxyl radicals (・OH). Hydroxyl radicals react very quickly with organic matter and can oxidize almost all organic matter, directly oxidizing organic matter in water into carbon dioxide and water, or decomposing large molecular organic matter into small molecules, making it easier to degrade.
In the treatment of industrial waste gas, ozone decomposition catalysts show many advantages. First, its reaction conditions are mild and it can work efficiently at room temperature. Compared with traditional treatment methods such as high-temperature incineration, it greatly reduces energy consumption and operating costs. Secondly, the catalyst has high catalytic activity and stability, and can maintain high catalytic performance for a long time, reducing the economic burden and operational troubles caused by frequent catalyst replacement. In addition, the application of ozone decomposition catalysts will not produce secondary pollution, which is in line with the current concept of green environmental protection.
Ozone decomposition catalysts are widely used in waste gas treatment in many industries. In the chemical industry, a large amount of waste gas containing volatile organic compounds (VOCs) and nitrogen oxides (NOx) is generated during the production process. Ozone decomposition catalysts can oxidize and decompose VOCs into carbon dioxide and water, and can also play a certain role in purifying NOx, effectively reducing the pollution of chemical waste gas to the environment. In the electronics and printing industries, there are also a large number of VOCs waste gas emissions. Ozone decomposition catalysts convert these waste gases into harmless substances through catalytic oxidation, achieving standard emissions of waste gas. In the sewers of urban sewage stations, foul-smelling gases are often emitted, which also contain a variety of organic pollutants. Ozone decomposition catalysts can treat and deodorize these organic waste gases and improve the air quality of the surrounding environment.
Take a chemical company as an example. The waste gas emitted by the company during the production process contains high concentrations of VOCs, which has a serious impact on the surrounding environment. After the introduction of ozone decomposition catalyst treatment equipment, the concentration of VOCs in the waste gas was greatly reduced, and the purification efficiency was as high as more than 90%, successfully meeting the national emission standards, and the surrounding environmental quality was significantly improved.
With the continuous improvement of environmental protection requirements, the application prospects of ozone decomposition catalysts in the field of waste gas treatment will be broader. In the future, scientific researchers will continue to conduct in-depth research, continuously optimize the performance of catalysts, improve their catalytic efficiency and stability, and reduce costs, so that they can better meet the waste gas treatment needs of different industries and different working conditions, and contribute more to our blue sky and white clouds.
