The presence of metallic Mo and MoO2 on SiO2 was found to be a prerequisite to the development of activity and selectivity for alcohol synthesis from CO-H2. The gradual increase in alcohol production during the reaction is ascribed to the formation of CO-reduction induced defects on MoO2. Experiments performed by adding olefins.to CO-H2 revealed that CO insertion into a metal-alkyl like bond constitutes the reaction pathway to alcohols. The role of K and CI in the promotion of alcohol production is discussed.
