Fumed Titanium Dioxide is an excellent white powder with hydrophilic groups on the surface, and the product does not have any pigment characteristics. The average particle size of the primary particle is about 21nm. The particle size and the density of 4g/cm3 give it a unique surface of 50m2/g.
Fumed titanium dioxide belongs to the mixed crystal type. The weight ratio of anatase to rutile is about 80: 20. Due to the mixing of the two structures, the defect density in the TiO2 lattice is increased, the carrier concentration is increased, and the number of electrons and holes is increased, which makes it have a more vital ability to capture the solution components (H2O, oxygen, organic matter) on the surface of TiO2.
Nano titanium dioxide has excellent properties such as ultraviolet absorption, photocatalytic sterilization, and decomposition of organic pollutants. It can be used in nano-coatings, air purifiers, self-cleaning glass, ceramics, and so on.
Nano titanium dioxide is widely used in the fields of antibacterial and anti-mildew, exhaust purification, deodorization, water treatment, weather resistance and anti-aging, automobile topcoat, and so on. It is widely used in the fields of environment, information, materials, energy, medical treatment, and health.

The wavelength range of light utilization can be enlarged by adding organic dye sensitizer or transition metal elements to Fumed Titanium Dioxide.
If Fumed Titanium Dioxide is attached to activated carbon, its catalytic performance will be significantly improved.
When hydrophilic fumed silica is added to Fumed Titanium Dioxide, its catalytic performance can also be improved.
