Abstract

The multimetal oxide materials essentially consisting ofMo12BiaX1bFecX2dX3eOy  (I)where:X1 is Co and/or Ni,X2 is Si and/or Al,X3 is an alkali metal,0.3≦a≦1,2≦b≦10,0.5≦c≦10,0≦d≦10,0≦e≦0.5 andy is the absolute value of the number which, assuming charge neutrality, is obtained from the sum of the valences and the stoichiometric coefficients of the other elements, the crystalline fractions containing, in addition to &bgr;-X1MoO4 as the main component, Fe2(MoO4)3 as a secondary component and no MoO3.
