Mössbauer Spectroscopy of Iron and Iron Alloy Fischer-Tropsch Catalysts

Mossbauer spectroscopy is an excellent technique for in situ investigations of iron-containing catalysts, because of the high penetrating power of the y-radiation and the high sensitivity of the spectral parameters to the chemical State and the local environment of the Mossbauer atom. Applications of Mossbauer spectroscopy in the field of catalysis up to 1980 have extensively been reviewed by Dumesic and Topsoe [1], and by Topsoe, Dumesic, and Morfrup [2]. Here we will review Mossbauer investigations of iron and iron alloy Fischer-Tropsch catalysts, carried out at the Interuniversitair Reactor Instituut at Delft.
