High-performance 20nm titanium dioxide nanoparticles offering optimal photocatalytic activity with improved handling for industrial applications

Titanium Dioxide 20nm (Non-Coated) is a high-performance nano-titanium dioxide powder engineered for optimal balance between photocatalytic activity and practical handling characteristics. With an average particle size of 20 nanometers, this material offers excellent surface reactivity while maintaining better dispersibility and reduced agglomeration tendency compared to smaller nanoparticles.

The 20nm particle size represents an ideal compromise for industrial applications, providing substantial photocatalytic efficiency while being easier to handle and process than ultra-fine nanoparticles. The non-coated surface ensures maximum accessibility of active sites for catalytic reactions, making this material particularly effective in environmental remediation and self-cleaning applications.

This nanoscale titanium dioxide demonstrates superior UV-blocking capabilities with high transparency to visible light, making it valuable in protective coatings, cosmetic formulations, and polymer stabilization. The enhanced surface area compared to conventional TiO₂ provides improved reaction kinetics for photocatalytic degradation of organic pollutants and antimicrobial activity under UV illumination.

Industrial Applications: UV-resistant coatings and paints, photocatalytic concrete and construction materials, air purification systems, wastewater treatment catalysts, self-cleaning glass and ceramics, antimicrobial hospital coatings, plastic and rubber UV stabilizers, and advanced catalyst supports.

Photocatalytic Properties: Efficiently generates reactive oxygen species under UV light for decomposition of organic compounds, NOx gases, and microbial contaminants. Shows excellent stability and reusability in continuous photocatalytic processes with minimal photocorrosion.

Processing Guidelines: More easily dispersible than smaller nanoparticles. Can be incorporated into water-based or solvent-based systems using high-shear mixing or ball milling. Pre-dispersion in appropriate medium recommended for optimal performance. Compatible with most organic and inorganic binders.

Safety Considerations: Nanomaterial requiring appropriate engineering controls. Use local exhaust ventilation when handling powder. Wear protective equipment including safety goggles, gloves, and dust mask. Avoid creating dust clouds. Follow established protocols for nanomaterial handling and disposal.

Storage: Keep in original sealed containers in a cool, dry environment. Protect from moisture to prevent caking. Material is stable under normal storage conditions. Some agglomeration may occur over time but can be reversed through appropriate redispersion techniques. Shelf life: 24 months.
