Abstract

The applicability of a reflux method for the preparation of cluster-derived Co-Ru catalysts supported on silica was studied. The properties of the resulting catalysts were compared with those of the corresponding catalysts prepared by impregnation. The presence of ruthenium either as a component of a bimetallic cluster or in a physical mixture of the two metals was essential for the adsorption of cobalt on silica. The activity and selectivity of these catalysts in CO hydrogenation were different from those obtained with catalysts prepared by impregnation.
