What is a photocatalyst?

Considerate of the environment, safe and secure! It decomposes and removes organic matter, demonstrating anti-soiling, deodorizing, and antibacterial effects.

"Photocatalysts" are materials that decompose organic substances when exposed to light, exhibiting effects such as anti-fouling, deodorization, and antibacterial properties. When titanium dioxide is exposed to light (ultraviolet), electrons (e-) and holes (h+) are generated. These electrons and holes react with oxygen and water in the air, producing reactive oxygen species such as superoxide anion (O2-) and hydroxyl radicals (·OH) on the surface of titanium dioxide. These reactive oxygen species possess strong oxidative power, removing and decomposing organic substances, thereby demonstrating anti-fouling, deodorization, and antibacterial effects. As a material that exhibits photocatalytic effects, titanium dioxide, which is chemically stable, has been widely used as a white pigment for a long time and is also a safe substance used in cosmetics and pharmaceuticals as a bulking and molding agent. *For more details, please refer to the PDF document or feel free to contact us.
