Abstract: The ferrite-type catalyst was found to have good activitty. The X-ray diffraction andMossbauer spectroscopy measurements show that the active structure of the catalyst is non-stoichiometric magnetite:FeA3+[Fe1-3δ2+Fe1 +2δ3+δ]BO4 The structure formed after substituting Cr3+ for Fe3+ seems to be an iron-chromium spinel-like mixed oxide:FeA3+[Fe1-x3+Fe2+Crx3+]BO4.

Key words: CO shift catalyst, Ferrite, Structure, Catalytic activity, Mossbauer spectroscopy
