Abstract
Trimetallic PtSnIn/Al2O3-Cl catalysts have been synthesized by successive impregnations (SI) of metals and characterized by 119Sn Mössbauer Spectroscopy (MS). Various Sn-species have been identified thanks to the use of a Δ (Quadrupole Splitting) – δ (Isomer shift) diagram. 119Sn MS results show that addition of different amounts of In (0.11 to 0.55 wt.%) lead to the formation of PtxSn(O) oxo-metallic phases. As the In loading increases these PtxSn(O) oxo-metallic phases are richer in Pt. The preferential formation of a given Sn phase in these catalysts is directly related to the preparation method.
