Nanoparticles can be applied widely to various fields thanks to their small sizes. The color of the titanium dioxide nanoparticles (TiO2 nanoparticles) is bright and the particles have a high refractive index (n=2.4). They can be used in toothpaste, pharmaceuticals, coatings, papers, inks, plastics, food products, cosmetics, and textiles. TiO2 has three crystalline phases, namely anatase (tetragonal), rutile (tetragonal), and brookite (orthogonal), among which brookite has no commercial value. Due to their self-cleaning and anti-fog properties, they are used to prepare cloth, car windows, tiles, and anti-fog mirrors. TiO2 nanoparticles can also be used as environmental disinfectants. Methods such as the sol-gel, flame hydrolysis, co-precipitation, impregnation, and chemical vapor deposition can be used to prepare nano-TiO2. Among them, the biosynthesis method has attracted wide attention from researchers due to its low cost, environmental friendliness, and good reproducibility. TiO2 nanoparticles have shown important industrial, environment, and agriculture value. They have been developed for applications in reducing the toxicity of dyes and pharmaceutical drugs, wastewater treatment, silkworm breeding, space applications, and the food industry.
In this summary, we discuss methods to synthesize TiO2 nanoparticles, including some commonly used modification techniques.
