Allgemeine Beschreibung

Vanadium(V) oxide is used as an oxidation catalyst for the oxidation of glyoxal to glyoxylic acid.

Anwendung

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.

A template-free strategy is exploited to bottom-up synthesize yolk-shell vanadium oxide through a two-step spontaneous assembly of hydrolytically formed subunits in a one-pot process. The unique structured vanadium pentoxide exhibits excellent cathode performance for lithium ion batteries.
