Photocatalyst means a substance that absorbs light energy and causes a photochemical reaction, and theoretically, organic pollutants can be completely decomposed into water and carbon dioxide. The typical optical catalyst is titanium dioxide (TiO2). TiO2 is used more frequently because it is resource-rich and cheap, has good durability, and abrasion resistance as an optical catalyst. There is no concern about secondary pollution when disposed of as a safety toxic substance. Especially considering the photocatalytic conditions and activity, it can be used semi-permanent even if it receives light, has strong sterilization due to higher oxidation power than chlorine or ozone, and eco-friendly because it breaks down all organic materials into carbon dioxide and water. Therefore, it has great ability in air purification, anti-staining function, hydrophilic function, water purification, deodorization, and antibacterial function.
Technology Specialties and Benefits
The Principle of Technology
Photocatalytic is a substance that causes a catalyst reaction by powerful oxidation-reduction reaction when subjected to light and TiO2 is a representative substance. Our Ecowell.Co.,Ltd Photocatalytic Honeycomb Filter is also made based on TiO2 and indicates odor removal, organic decomposition, sterilization, etc. during UV-LED 350~380mm light irradiation. TiO2(Titanium dioxides) is used in many places such as cosmetics, white paint and food additives, and is a substance known to be chemically stable and harmless to the environment and human body.
