Abstract Data on the kinetics and mechanism of reactions in the hydrogenation of carbon monoxide, carbon dioxide, and aliphatic carbonyl and nitrile compounds over transition metals have been summarized and correlated. The ranking of specific catalytic activity and selectivity with respect to the addition of hydrogen to CO, CO2, and the 〉 C=O and -C≡N groups is determined mainly by the energies of the bonds between the metal and the compound being hydrogenated, and between the metal and hydrogen. In turn, the bond energies depend on the chemical nature of the metal and also on the degree of dispersity of the metal. The role of the dimensional factor, which influences the concentration of active centers, has also been investigated. On the basis of the relationships that have been found between the physicochemical and catalytic properties of monotypical substances, criteria have been formulated for the selection of catalysts for the hydrogenation of these compounds.
