Abstract
The invention concerns a compound comprising a combination of two crystal phases. The first crystal phase corresponds to the formula: AEVMoPOHwherein A is an alkali-metal; E is Te, Sb or Bi; and 0≦a≦3, 0<b≦3, 0≦c≦3, 0<d≦13, 0<e≦2, 0≦g≦3. The second crystal phase corresponds to the formula ZMoXOwherein: Z is selected among trivalent rare earths; X is selected among the elements V, Ga, Fe, Bi, Ce, Ti, Sb, Mn, Zn, Te; and 0<g≦3, 0≦h≦3, 0≦i≦1. The indices f and j represent the number of oxygen atoms required for satisfying the relative valency and atomic proportions of the elements present. The invention also concerns the method for preparing said compound, and its use in particular as catalyst for oxidizing alkanes.
