Integrated CO₂ capture and one-pot production of methanol

The capture, storage, and utilization (CSU) of CO₂ to produce methanol which can be used as a fuel, fuel additive, and precursor in organic synthesis is an area of fascinating research. This directly influences the reduction of the CO₂ concentration by capturing CO₂ from industrial and automobile emissions. The development of integrated CO₂ capture and conversion to a fuel and fuel additive has garnered considerable attention as it eliminates costly processes to produce pure CO₂. This contribution presents a summary of integrated CO₂ capture and conversion to methanol (MeOH) using amine-assisted and alkali hydroxide-assisted one-pot systems. The superiority of the alkali hydroxide-based system to the amine-based system for the conversion to MeOH is systematically presented.
