Growth and electrochemical properties of single-crystalline vanadium pentoxide (V2O5) nanorod arrays were investigated. Vanadium pentoxide nanorod arrays were grown by electrochemical deposition, surface condensation induced by a pH change and sol electrophoretic deposition. Uniformly sized vanadium oxide nanorods with a length of about 10 mm and diameters of 100 or 200 nm were grown over a lar...

Vanadium is the 22 most abundant element in the earth’s crust with an average concentration of 100 ppm. It exists in oxidation states ranging from 2to 5+ with 3+, 4+, and 5+ being the most common oxidation states. Vanadium is primarily used in the production of rust-resistant, spring, and high-speed tool steels; vanadium pentoxide is used in ceramics. Vanadium is released to the environment by ...

Shewanella oneidensis couples anaerobic oxidation of lactate, formate, and pyruvate to the reduction of vanadium pentoxide (V(V)). The bacterium reduces V(V) (vanadate ion) to V(IV) (vanadyl ion) in an anaerobic atmosphere. The resulting vanadyl ion precipitates as a V(IV)-containing solid.

A one-step, room-temperature method is described to chemically synthesize bulk quantities of microns long, 100-180 nm diameter nanofibers of electrically conducting poly(3,4-ethylenedioxythiophene)(PEDOT) in the form of powders, or as optically transparent, substrate-supported films using a V2O5 seeding approach.

Fuel oil used in power plants contain metal impurities like Vanadium. After combustion, this metal remains in boiler fuel ash in the form of oxide. In this research, extraction of Vanadium oxide from fuel ash has been investigated. Two processes were used for this purpose. A pyro- hydrometallurgy and a hydrometallurgy process. In the pyro-hydrometallurgy process, using sodium carbonate, salt ro...

Investigated effects of varying C-rates on stress and structure changes in V2O5. A linear increase in the stress as a function of x in LixV2O5 is observed. C-rate does not directly contribute to larger intercalation stress. A rapid increase in disorder within LixV2O5 is correlated with higher Crate. a r t i c l e i n f o

The application of analytical transmission electron microscopy in characterisations of catalytic materials is presented by studying the mechanically activated vanadium pentoxide V2O5. Local morphology and lattice distortion are studied by TEM while the oxidation states are determined by EELS. The mechanical activation can be described as a two -stage process: crushing of large crystals into sma...

The solution used in a vanadium flow battery is vanadium oxide, V2O5, dissolved in sulfuric acid and water. All conventional batteries must contain two unique solutions. Production of the solution is more space and time efficient, and it is impossible to contaminate the battery within itself. Another advantage is that the reaction is in aqueous solution and requires no phase changes. We are cur...
