General description

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

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.
