General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Click here for more details.

Application

Selective ammoxidation catalysts for such reactions as conversion of toluene to benzonitrile or propylene to acrylonitrile were prepared by a sol-gel method from V2O5, Sb2O3 and high purity hydrogen peroxide. Preparation of new stabilized, oxide ion-conducting, bismuth vanadate phases by a microwave assisted method, fromV2O5, Bi2O3 and other solid oxides, was reported. These ceramics show promise in solid oxide fuel cells, water-vapor electrolyzers and oxygen sensors.

Here we report a new strategy to improve the electrochemical stability of vanadium oxide electrodes for pseudocapacitors. Vanadium oxides are known to suffer from severe capacitance loss during charging/discharging cycling, due to chemical dissolution and ion intercalation/deintercalation-induced material pulverization. We

The bactericidal activity of TiO(2) nanoparticles under visible light is very important in regards to its practical applications. In this paper, we synthesized vanadium-pentoxide-loaded TiO(2) nanoparticles (V(2)O(5)-TiO(2)) using a chemical vapor condensation method, followed by the impregnation method, and characterized
