Abstract

Catalysts with the composition MeII11-x Fex BiMo12On in which MeII= Ni, Co, Mg or Mn and 0 <× <4 are investigated. It is shown that preparation by coprecipitation followed by evaporation is necessary to obtain high activity and selectivity for the oxidation of propene to acrolein. Catalytic properties in combination with X-ray diffraction and ESCA measurements lead to a three-layer model for the catalyst particles. In this model the surface layer consists of Bi-molybdates, the second layer of Fe-molybdate and the core of MeII-molybdate. From the high specific activity of this type of catalysts compared with pure Bi-molybdates it is concluded that Fe-molybdate acts as a promotor. A possible explanation for this promoting effect is given.
