Black Titanium Dioxide Nano Pigments; Synthesis, Characteristics and Applications

Black titanium dioxideNano pigments can retain daylight from UV to infrared wavelengths, since its optical absorption properties, and is presented as a good light absorber contrasted with titanium dioxide. Ongoing improvements in the field of black titanium dioxide have plainly shown that these materials are generally utilized in innovative work, because of their exclusive structural properties, for instance, surface disordered, oxygen vacancy and Ti3+ ions and their appropriate electronic properties, which are because of their narrow band gap, have been utilized in different applications, for example, photodegradation of dyes, photocatalytic and photoelectrochemical water splitting, batteries, super capacitors, fuel cell, hydrothermal treatment of cancer, and solar cells. Various approaches have been reported to prepare black TiO2 such as hydrogenation, chemical reduction with different metal like Al, Zn and Mn, chemical oxidation, ultrasonication, anodization-anilling and laser modification. This paper focused on the synthesis method, properties and applications of these Nano pigments briefly.
