Visible Light Catalyst

BlueTiO visible-light photocatalyst

Advanced visible-light photocatalyst for indoor air & surface applications

BlueTiO is a next-generation visible-light photocatalyst engineered from selectively phase-reduced P25 TiO₂, designed to remove airborne contaminants and support hygienic environments under normal indoor lighting.

World’s first “Blue P25 TiO₂” based on selective reduction of one crystal phase (Rutile–Anatase system).
Demonstrated activity for removal of bacteria, viruses, and volatile compounds under visible light.
Applicable as powders, films, and coated modules for a variety of device and product designs.

APPLICATION EXAMPLE

Strawberry preservation test under visible light

Without BlueTiO film

In a closed transparent container at room temperature and room light, bacteria begin to grow around strawberries after 4–5 days, leading to visible spoilage.

COMMERCIALIZED FROM THE BLUETIO PLATFORM

VisTiO – Visible Photocatalyst Spray

VisTiO is a visible-light photocatalyst spray developed from the BlueTiO technology platform and successfully translated from laboratory research into a ready-to-use consumer product for everyday indoor spaces.
Developed using a photocatalyst technology that has been validated in laboratory environments for its strong activity against common indoor contaminants.
Helps remove unwanted odors and keep interior environments feeling fresher in rooms, shared spaces, and enclosed areas exposed to light.
