The reactivity of molecular clusters with the surface of oxides such as silica, alumina is at the origin of a new class of hybrid catalysts which exhibit unusual activities and selectivities in comparison with conventional homogeneous and heterogeneous catalysts. It is the purpose of this paper to deal with this aspect of cluster chemistry in connection with the mechanism of CO reduction in heterogeneous catalysis. Such a surface reaction between a molecular carbonyl and the surface of an inorganic oxide raises a number of questions which are relevant to Fischer-Tropsch synthesis, since it has been claimed that molecular cluster carbonyls are the effective catalysts for hydrocondensation of CO to hydrocarbons or alcohols.
