Abstract

Ru3(CO)12, Fe2Ru(CO)12 and H2FeRu3(CO)13 deposited on Cab-O-Sil and A12O3 have been investigated. Infrared and Mössbauer spectroscopy revealed a strong interaction between a molecular cluster and alumina which leads to the disintegration of the cluster framework up to monoruthenium subcarbonyl species and iron oxide. Temperature-programmed decomposition showed carbon retained in alumina-supported catalyst whereas with Cab-O-Sil the ligands from the adsorbed cluster could be recovered. After temperature-programmed decomposition in hydrogen and vacuum, CO adsorption resulted in four IR bands at about 2138, 2075, 2020 and 2043 2050 cm-1. From these data the formation of highly dispersed bimetallic particles on alumina is discussed.
