What is photocatalyst?

Photocatalyst, also known as "photocatalysis", mainly utilizes solar energy for environmental purification and energy conversion. 

Photocatalyst technology has been widely applied in the civilian sector in developed countries and regions such as Japan. Its active ingredients, upon absorbing ultraviolet rays from sunlight or artificial lighting sources, undergo oxidation and reduction reactions, generating hydroxyl radicals and superoxide radicals. These radicals can react with organic substances, breaking the molecular bonds of organic compounds (such as C-C, C-H, C-N, C=O, N-H, etc.), and decomposing harmful substances and microorganisms in the air into harmless carbon dioxide and water. The working mechanism is illustrated as follows: 

In response to market demands and customer needs, our company has been the first in China to develop a photocatalyst finishing agent that can be used in textile processing. It functions effectively under both visible light and ultraviolet light conditions.                                                                     

The following is the performance test result of the developed photocatalyst finishing agent applied to textiles:
