The high throughput synthesis and characterization of a particular family of ceramic materials, bismuth
molybdenum vanadium oxides (BiMoVOX), suitable as inorganic yellow pigments and low temperature oxidation
catalysts, is described. Samples, synthesized by calcination and peroxo sol-gel methods, are characterized by X-ray
powder diffraction, UV-visible and XAFS spectroscopy. A combined high-throughput XRD/XAFS study of a 54
samples array, with simultaneous refinement of data of both techniques, has been performed. Molybdenum doping of
bismuth vanadate results in a phase transition from monoclinic BiV04 to tetragonal Bi(V,Mo)04, both of scheelite type.
Both central metals, V5+ and Mo6+, remain in a tetrahedral coordination. UV/visible spectroscopy identifies a linear blue
shift as a function of Mo6+ amount
