Nano titanium oxide (nano-TiO2): A review of synthesis methods, properties, and applications

Nanoparticles have revolutioned materials secience and manufacturing industry thanks to their ultrafine scale. Nano-scale titanium oxide (nano-TiO2) are key elements of a wide variety of sectors of advanced materials, devices, and systems in view of their versatility and extraordinary characetristics, mainly optical, electrical and catalytic properties. Thnaks to aforementioned features, they found a key position in different industries such as colors and pigments, photocatalysts, photovoltaic solar cells, adsorbents, cosmetics, electric and electronic devices. Nano-SiO2 application gives rise to a wide range of properties and performance, which severely depends on particle size, particle size distribution, and agglomeration in the bulk of host materials or systems. When they are used as surface coating additive or even functionalized, nano- TiO2 takes more roles, which are state-of-the-art depending on synthesis method. Therefore, review of synthesis, properties, surface- and bulk-functionalization/modification (respectively with function groups and doping) methods in achieving high-performance nano- TiO2 seems essential. In this review, background information and developments from pure Titanium Oxide to chemically modified Titanium Oxide -based materials as photocatalysts were discussed in detail, Photocatalytic activity of Titanium oxide-based materials in nitrogen group pollutant decomposition. It also Titanium Oxide Nanoparticles as a Vehicle for Chemotherapeutics and Other Applications of Titanium Oxide Nanoparticles in Medicine and also an overview of the synthesis methods and factors affecting their properties in different synthesis methods have been reviewed.
