Bimetallic catalysts supported on oxide carriers reveal a superior behavior if molecular carbonyl clusters are used. The resulting small metallic particles can be stabilized and the unique feature not only results in higher specific activity in carbon monoxide hydrogenation, but deactivation occurs to a lesser extent and the selectivity can be also controlled towards the formation of preferred products. In the paper, characterization of supported mono- and bimetallic catalysts derived from molecular cluster by Moessbauer and infrared spectroscopy as well as by temperature programmed spectroscopy (TPR, TPO, TPD, etc. ) are discussed and direct evidence is given for the formation of bimetallic particles in the range of 2 nm particle diameter. A comparison between the cluster derived catalyst and those prepared in traditional ways is provided.
