Volume 93 Issue 3 April 1984 pp 321-334 Solid Statet Chemistry and Surface Chemistry
G Sankar P R Sarode A Srinivasan C N R Rao S Vasudevan J M Thomas
A detailed investigation of sulphided Co/Mo/Al2O3 catalysts, their oxide precursors and several model oxides and sulphides of cobalt and molybdenum has been carried out using x-ray photoelectron spectroscopy and x-ray absorption spectroscopy (
xanes andexafs ). Octahedrally coordinated Co(II) and Mo(IV) are shown to be present in a sulphidic environment on the surfaces of these catalysts. The surface species contain an excess of sulphur, probably involving disulphide linkages. The surface compositions of the catalysts examined conform to the general formula Co11 Mo2nIV (2n + 3)S 22− (2n -2)S2−. -
