Titanium dioxide (TiO2)

Rutile TiO2 is a kind of crystal morphology of titanium dioxide, which has a tetragonal crystal system structure, in which titanium ions are located in the center of octahedron and surrounded by six oxygen ions. The characteristics of Rutile titanium dioxide include high refractive index, excellent ultraviolet light absorption, good chemical stability, and high Electron mobility. Rutile type titanium dioxide is widely used in the fields of photoelectric conversion and photocatalysis, such as solar cells and photocatalysts. Its excellent optical properties also make it used as a white pigment in coatings, plastics, paper, and ink. In addition, it is also used in optoelectronic devices such as photodiodes and lasers, as well as in photocatalytic applications such as hydrogen production through water photolysis and photocatalytic degradation of organic pollutants.
