Visible light responsive photocatalyst (CelMuse™)

Visible light responsive photocatalyst (CelMuse™)

While conventional photocatalysts are mostly of outdoor ultraviolet light responsive type, Daicel has succeeded in developing a visible light responsive catalyst that responds to fluorescent light and low-intensity indoor light, such as LEDs. It is used for a variety of purposes, including interior and coating materials and filters.

Features of CelMuse™

Features of CelMuse™

High activation performance by the particle shape control technology (forming rod shaped)
Visible light response performance by the loaded supported iron compounds
High activation performance by selective loading iron on specific surface
Realized Low cost by combination of titanium oxide and iron

Pprinciple of CelMuse™

Reaction of normal TiO2 photocatalyst
Reaction of normal TiO2 photocatalyst Electron holes and electrons are present in the same place. ⇒ recombination is likely to occur.【Disappearance of active species】
Control technology for Particle shapeControl technology for Particle shape
Reaction of rod type TiO2 photocatalyst
Reaction of rod type TiO2 photocatalyst Presence of electron holes and electrons separated. ⇒ less likely to cause recombination.【High activation for reaction】
