The influence of supports and preparation methods on the chemical state of the promoter for Pt-Sn catalysts has been studied by Mössbauer spectroscopy. No regular trend or pattern is found for the supports studied. Impregnation with a complex compound results in the highest content up to 55% of Sn(O)+Sn (II) in the catalyst. However, if the Sn (IV) state is desired, such catalysts can be prepared and the Sn (IV) state can be stabilized using a specific preparation method. |
