摘要
The present invention comprises the elements molybdenum, vanadium, niobium and tellurium and has, in XRD, the diffraction reflections h, i, k and l when using Cu-Kα radiation, the peaks of which are approximately the diffraction angle (2θ). 26.2 ° ± 0.5 ° (h), 27.0 ° ± 0.5 ° (i), 7.8 ° ± 0.5 ° (k) and 28.0 ° ± 0.5 ° (l) ), Wherein the stoichiometric ratio is: Mo1VaNbbTecOn (I) (where a = 0.2-0.35, b = 0 to 0.08, c = 0 Up to 0.08 (n = number determined by the valence and abundance of the non-oxygen element in (I)).
