In the recent years, scientists have intensified their research in the field of nanoparticles mainly due to the innovative and unexpected results that are achieved through altering the atomic and molecular properties of various elements. This article looks into the properties and applications of vanadium oxide nanoparticles.
Vanadium forms a number of different compounds with oxygen, depending on the oxidation state of the vanadium metal. The most common of these are listed below - other stoichiometries can be found in vanadium oxide crystal phases in addition to these.
- Vanadium (II) oxide (vanadium monoxide), VO
- Vanadium (III) oxide (vanadium sesquioxide or trioxide), V2O3
- Vanadium (IV) oxide (vanadium dioxide), VO2
- Vanadium (V) oxide (vanadium pentoxide or vanadic anhydride), V2O5
The most stable, and therefore most common, form of vanadium oxide is vanadium (V) oxide, V2O5. Vanadium (V) oxide nanoparticles are available are dispersed, high purity carbon coated and nanofluid. Vanadium belongs to Block D, Period 4 while oxygen belongs to Block P, Period 2 of the periodic table.
The following tables list the chemical properties of vanadium oxide.

Vanadium oxide nanoparticles appear in the form of a black powder having a spherical surface. The physical properties of vanadium oxide are listed below.
The thermal properties of vanadium oxide nanoparticles are as below.
Vanadium oxide is used extensively as a catalyst in many industrial chemical reactions. It is also used in the following applications:
- In optical applications such as making of laser crystals
- In nanofiber and nanowire applications
- In the manufacture of some alloys and ceramics
