With the chemical formula TiO2, titanium dioxide is a naturally occurring oxide of the metal titanium. It is a common substance that is utilized in a wide range of commercial and consumer applications. It is white, transparent, and non-toxic. Due to its high refractive index, opacity, and brightness, titanium dioxide is the most often used white pigment. This makes it perfect for adding color and concealing power to a variety of goods. Numerous environmental applications have made advantage of its photocatalytic and photoelectron chemical capabilities as well. It is present in many goods, including paints, coatings, plastics, cosmetics, and food. Titanium dioxide is now a necessary ingredient in the creation of a variety of products, and its significance in numerous sectors is only growing.

Computational method used in the calculation of TiO2

To calculate titanium dioxide (TiO2), a variety of computational techniques are utilized, depending on the particular application and necessary level of precision.

Density Functional Theory (DFT), a quantum mechanical methodology that determines the electronic structure and characteristics of materials, is one of the most used techniques. DFT computations may provide details about the band structure, density of states, and charge distribution of TiO2, among other electrical and structural characteristics.

Molecular Dynamics (MD), which mimics how atoms and molecules behave over time, is another frequently utilized technique. The structural and dynamical characteristics of TiO2 at various pressures and temperatures may be studied using MD simulations.

Ab initio calculations, which employ first principles techniques to compute the characteristics of materials, and Monte Carlo simulations, which can offer information on thermodynamic parameters, are other computational techniques that are occasionally used in the calculation of TiO2.

Overall, because each computing approach has advantages and disadvantages, it is important to consider the specific research topic at hand as well as the needed level of accuracy.

Uses of Titanium dioxide

A versatile and often used substance with a wide variety of uses in several sectors is titanium dioxide (TiO2). TiO2 is utilized for a variety of purposes thanks to its special optical, electrical, chemical, and physical characteristics as well as its availability, low toxicity, and stability.

The following are some of the main rationales for using TiO2:
