This is a case study of photocatalytic application for anti-fouling measures on glass at a construction company research facility.
The hydrophilic effect of photocatalysts (self-cleaning effect) makes it easier for rain to wash away dirt from building exteriors and glass, creating a clean environment.
By applying a titanium dioxide aqueous solution, which is the raw material for photocatalysts, to the ceilings and walls of buildings, it exhibits effects such as anti-soiling, deodorization, antibacterial properties, antiviral properties, and mold prevention. When light hits the surface of the indoor photocatalyst application, reactive oxygen species are generated on the surface, decomposing organic substances that cause dirt and odors into harmless water and carbon dioxide. Additionally, the surface of the outdoor photocatalyst application has a hydrophilic effect that allows water to spread thinly beneath the dirt when it rains, contributing to self-cleaning as the dirt flows away along with the water, thus maintaining the aesthetic of the building and reducing cleaning costs. Since the raw material for the photocatalyst, titanium dioxide, is inorganic, it does not degrade due to ultraviolet rays or other factors, and its effects continue for a long time.

basic information
The photocatalytic effects of anti-soiling, deodorization, antibacterial, antiviral, and mold prevention are utilized for maintaining the aesthetics and improving the environment inside and outside buildings. The self-cleaning effect (hydrophilic effect) of exterior photocatalysts, combined with the power of rain, provides anti-soiling effects for buildings. The organic decomposition capability of indoor photocatalysts effectively contributes to deodorization, antibacterial, antiviral, and mold prevention inside buildings. *For more details, please refer to the PDF document or contact us.
