Purify Air and Surfaces with Evonik’s Photocatalytic Solutions
In urban environments, industrial zones, and indoor spaces, photocatalysis offers a path to air purification and surface hygiene. Evonik’s nanostructured titanium dioxide products, supplied as AEROXIDE® powders, VP AEROPERL® granulates and AERODISP® dispersions, break down VOCs, NOx and odour compounds when activated by UV light. 
Why Choose Evonik for Photocatalytic Applications?
- Proven Performance: AEROXIDE® TiO₂ P 25 is widely used in photocatalysis research and is frequently referred to as the "gold standard" in the field. Evonik’s nanostructured titanium dioxide products have an average primary particle size of 14–21 nm, and AEROXIDE® TiO₂ P 25 has a BET surface area of 35–65 m²/g – a very different profile from pigmentary titanium dioxide (0.2–0.5 µm).
- Tailored Innovation: Our materials adapt to diverse applications—from air cleaners and coatings to building materials and filters.
