Mössbauer Spectroscopy in Heterogeneous Catalysis

“…The characterization of tin-containing catalysts by Mo¨ssbauer spectroscopy has been focused mainly on supported bimetallic alloys (150)(151)(152)(153)(154)(155)(156)(157)(158)(159)(160)(161)(162). These catalysts, which consist of Pt, Pd, Rh, or Ru as primary metals with Sn used as a promoter, are generally supported on SiO 2 or Al 2 O 3 .…”

“…These catalysts, which consist of Pt, Pd, Rh, or Ru as primary metals with Sn used as a promoter, are generally supported on SiO 2 or Al 2 O 3 . These catalysts are used in reforming and hydrogenation processes in the petroleum industry (151,152) and have recently drawn attention for other applications, such as low-temperature CO oxidation, alkane and alcohol dehydrogenation, metathesis reactions (153)(154)(155)(156)(157)(158)(159)(160), and even nitrate removal for drinking water processing (161).…”
