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 ...
KINETICS OF OXIDATION OF D-ARABINOSE AND D-XYLOSE BY VANADIUM (V) IN THE PRESENCE OF MANGANESE II AS HOMOGENEOUS CATALYST
(Sociedad Chilena de Química, 2010)
Thermal treatments of precursors of molybdenum and vanadium oxides and the formed MoxVyOz phases active in the oxydehydration of glycerol
(2017-02-25)
This paper presents an in situ study of the crystallographic phases formed during the thermal treatment of precursors of vanadium and molybdenum oxides, measured under synchrotron X-ray diffraction. The interest in the ...
Insights into Redox Dynamics of Vanadium Species Impregnated in Layered Siliceous Zeolitic Structures during Methanol Oxidation Reactions
(2020-01-08)
Supported transition metal catalysts have been extensively applied to oxidative and reductive processes. The understanding of surface speciation and active site-support interactions in these materials play a substantial ...
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 ...
