| Abstract: | In hydrogenation over metals (M)j carbon monoxide is adsorbed as a molecule. C–O bond rupture in partially hydrogenated complex, MCHOH, leads to MO and MCH2 and then to hydrocarbons, while transformation of MCHOH into MCH2OH gives alcohols and other oxygen-containing compounds. Selectivity towards hydrocarbons increases with increasing energy of M–O bonds.
