HYDROTHERMAL SYNTHESIS OF VANADIUM-OXIDES

The use of mild hydrothermal methods to synthesize vanadium oxides is reviewed, with particular emphasis on those with layer and S-dimension al structures. A wide range of studies has been performed predominantl y in the past decade to grow new materials that might have interesting electrochemical and magnetic :properties. Most emphasis has been plac ed on vanadium oxides that contain organic species or simple cations s uch as the alkali metals, alkaline earths, zinc and copper. The key pa rameters determining the structures formed are reviewed, including pH and the organic structure-directing ion. Some initial electrochemical studies are described.
