Spectrophotometric determination of vanadium(IV) in the presence of vanadium(V) using Br-PADAP
(1998)
In the present paper, a simple and sensitive method is proposed for vanadium(IV) determination in the presence of vanadium(V). This is based on the oxidation of vanadium(IV) present in the sample to vanadium(V) by addition ...

The role of vanadium on the properties of iron based catalysts for the water gas shift reaction
(Elsevier, 2005-04-08)
The substitution of chromium by vanadium as dopant in the iron oxide based water gas shift (WGS) catalyst has been investigated. Catalysts prepared as magnetite with different amount of vanadium have been prepared and ...
Effect of titanium-doping on the properties of vanadium antimonate catalysts
(Elsevier Science, 2000-02)
Catalysts of nominal compositions VSb1 - xTixO4, with x = 0, 0.1, 0.2 and 0.4, were prepared by solid state reaction of vanadium(V) oxide, antimony(III) oxide and titanium(IV) oxide mixtures. Their structural and catalytic ...
