Tungsten oxide (WO x ) is a transition metal oxide with wideranging applications. With the advent of nanotechnologies, the synthesis and analysis of WO x nanostructures has become increasingly prominent. Nanostructuring of WO x can enhance the performance of this important functional material and provides it with unique properties that do not exist in its bulk form. Exceptional qualities of nanostructured WO x compared to the bulk material include: i) increased surface-to-volume ratio, which provides more surface area for both chemical and physical interactions; ii) signifi cantly altered surface energies that allow tuning and engineering of the material’s properties, as atomic species near the surface have different bond structures than those embedded in the bulk; and iii) quantum confi nement effects, due to the inherently small size of nanostructured materials, that signifi cantly infl uences charge transport, electronic band structure and optical properties.  Nanostructured WO x is exceptionally versatile and offers unique characteristics. It has become one of the most investigated functional metal oxides impacting many research fi elds ranging from condensedmatter physics to solid-state chemistry.
