In recent years, carbon dioxide (CO2) has become the focus of much attention because of the position of CO2 as the primary greenhouse gas and the implication of its emissions on the problem of climate change.[1] Various sequestration technologies for CO2 abatement are being considered. It has been recently demonstrated that hydrogen gas can be manufactured on large scales from renewable sources, including solar energy, hydropower, and biomass.[2] Thus, complete or partial recycling of CO2 through its hydrogenation to high-energydensity liquid fuels appears to be a very attractive approach. As a result, catalytic CO2 hydrogenation reactions to methanol, higher alcohols, gasoline, and related higher hydrocarbons (Fischer–Tropsch-like reactions) have been receiving much renewed attention. Particularly, the focus is on the production of methanol, which is a key platform chemical for present fuel and chemical infrastructures.[3] A recent assessment of economic feasibility for this new green process supports the possibility.[4]Today, methanol is produced industrially from syngas containing CO and CO2 (derived from fossil fuels) over Cu/ZnO/Al2O3 catalysts.[5, 6] These Cu/ZnO based systems are also evaluated to be the most efficient catalysts for the direct hydrogenation of CO2 [Eq.(1)].[7] Although the two reactions
