Mössbauer Spectroscopy of Iron and Iron Alloy Fischer-Tropsch Catalysts

Mössbauer 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 Mössbauer atom. Applications of Mössbauer spectroscopy in the field of catalysis up to 1980 have extensively been reviewed by Dumesic and Topsøe [1], and by Topsøe, Dumesic, and Mørfrup [2]. Here we will review Mössbauer investigations of iron and iron alloy Fischer-Tropsch catalysts, carried out at the Interuniversitair Reactor Instituut at Delft.
