Photocatalysts FAQ
Q: What makes your photocatalysts superior to conventional alternatives?
A: Our photocatalysts incorporate proprietary surface modifications and dopants that significantly enhance quantum efficiency while extending the absorption spectrum into visible light. The precisely engineered nanostructure provides more active sites per unit area compared to standard formulations, resulting in 30-50% higher reaction rates under identical conditions.
Q: How should photocatalysts be stored and handled?
A: Photocatalysts should be stored in airtight containers away from moisture and direct sunlight. Optimal storage temperature ranges between 15-25°C. When handling, use appropriate PPE as nanoparticles may become airborne. For best results, activate the material under UV light for 15-30 minutes before first use.
Advanced Application Areas
