This is a case study of photocatalytic treatment for dirt prevention on apartment building exteriors.
The decomposition of organic contaminants using photocatalysts and self-cleaning creates a clean environment by breaking down substances that cause dirt, odors, bacteria, and mold both inside and outside buildings.
By coating the ceilings and walls of buildings with a titanium dioxide aqueous solution, which serves as the raw material for photocatalysts, it exhibits effects such as dirt resistance, 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. The surface of the outdoor photocatalyst application has a hydrophilic effect, where rainwater spreads thinly under the dirt, contributing to self-cleaning as it washes away the surface dirt, 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 aesthetic appeal and improving the environment both inside and outside buildings. The self-cleaning effect (hydrophilic effect) of exterior photocatalysts, combined with the power of rain, provides anti-soiling benefits for buildings. The organic decomposition capability of indoor photocatalysts effectively contributes to deodorization, antibacterial, antiviral, and mold prevention within the building. *For more details, please refer to the PDF document or contact us.*
