With high catalytic efficiency and redox capacity, nano titanium dioxide shows great potential in the fields of water treatment, air purification, self-cleaning materials, and medical antibacterial.
Water Treatment
Deep purification of industrial wastewater: Nano titanium dioxide has shown great ability in industrial wastewater treatment. It can efficiently decompose methylene blue in printing and dyeing wastewater (degradation rate >95%), organophosphorus in pesticide wastewater (80% decomposition in 60 minutes), and antibiotics (tetracycline half-life of 30 minutes). In addition, the reduction efficiency of Cr⁶⁺ in electroplating wastewater is up to 90%, generating low-toxicity Cr³⁺ and removing it by precipitation.
Petrochemical wastewater treatment: In petrochemical wastewater treatment, nano titanium dioxide can decompose petroleum hydrocarbon pollutants, combined with membrane separation technology to achieve efficient separation of oil and water, and reduce treatment costs by 30%.
Air Purification
The use of nano titanium dioxide in the surface coating of tunnel lighting can break down NOx from automobile exhaust (40% improvement in degradation efficiency).
Adding nano titanium dioxide to indoor paints, the formaldehyde removal rate can reach 70%.
self-Cleaning Materials
With TiO₂ coating on architectural curtain wall glass, rainwater automatically washes away surface stains, making maintenance intervals three times longer.
Medical Antibacterial
After using TiO₂ coating on the surface of medical catheters and ceramic baths, the inactivation rate of Staphylococcus aureus is >99.9%, which greatly reduces the risk of infection.
