Integrated carbon capture and utilization to methanol with epoxide-functionalized polyamines under homogeneous catalytic conditions
Journal of Organometallic Chemistry(2022)
Abstract
•Integrated CO2 capture and utilization (CCU) to synthesize methanol.•Reaction of pentaethylenehexamine (PEHA) with selected epoxides led to a library of functionalized polyamines for CO2 capture.•CO2 captured aqueous amine solutions were directly converted to methanol via catalytic hydrogenation to CH3OH in presence of molecular H2 and Ru-PNP based molecular catalysts.•Improved amine-based aqueous system for CO2 capture and hydrogenation is key in advancing low temperature and renewable methanol synthesis process.
