Abstract

Temperature Programmed Decomposition (TPDC) of iron and ruthenium carbonyl clusters (MCC) in crystalline and supported forms as well as activity of the mono- and bimetallic catalysts formed in CO/H2 reaction and n-butane hydrogenolysis have been investigated. The catalytically active phase is produced by partial decarbonylation of MCC at about 370 K in H2 and He. At higher temperatures further decomposition occurs accompanied by interaction with the support. This is confirmed by XPS and DSC measurements. The CO adsorption and the catalytic activity for CO/H2 and C4H10/H2 reactions on the catalyst formed in He is higher than those in H2 as well as on that prepared from inorganic salts. Interaction between Fe and Ru is also reflected in the selectivity values.
