Abstract (en)

[origin: WO2018141652A1] The invention relates to a mixed oxide material comprising the elements molybdenum, vanadium, niobium and tellurium, which mixed oxide material has diffraction reflections h, i, k and l in XRD analysis in the presence of Cu-Kα radiation, said diffraction reflexes having their vertices approximately at the diffraction angles (2⋅) 26.2° ± 0.5° (h), 27.0° ± 0.5° (i), 7.8° ± 0.5° (k) and 28.0° ± 0.5° (l), characterized in that: Mo1VaNbbTecOn (I). a = 0.2 to 0.35, b = greater than 0 to 0.08, c = greater than 0 to 0.08, and n = is a number that is determined by the valency and frequency of the elements in (I) that are different from oxygen.
