What is Photocatalysis Air Cleaner?

2023-03-11

Photocatalysis air cleaners use photocatalytic oxidation to remove pollutants from the air. This Air Purifier technology involves the use of a catalyst, usually titanium dioxide (TiO2), and ultraviolet (UV) light to break down volatile organic compounds (VOCs) and other pollutants into harmless substances like carbon dioxide and water.

When UV light shines on the TiO2 catalyst, it generates highly reactive electrons and holes. These electrons and holes then react with oxygen and water in the air to produce highly reactive species like hydroxyl radicals and superoxide ions, which break down pollutants into harmless substances.

Photocatalysis Air Cleaner are effective at removing a wide range of pollutants, including VOCs, bacteria, viruses, and even some odors. They are also energy-efficient and environmentally friendly, as they do not produce any harmful byproducts.

However, it is important to note that photocatalysis air cleaners are not a panacea and should be used in conjunction with other air cleaning methods, such as air filtration, to achieve optimal results. Additionally, the effectiveness of photocatalysis air cleaners can vary depending on factors like the intensity and wavelength of the UV light, the surface area of the TiO2 catalyst, and the concentration of pollutants in the air.
