Key Points

  • CO2 release is effectively enhanced through the proton coupled electron transfer mechanism applied to amines.
  • MDEA with P-doped graphite felt achieves the optimal interface for enhancing CO2 desorption efficiency.
  • Analysis focused on two amines and three modified graphite felts shows a significant reduction in energy consumption.
  • Findings suggest further exploration of amine solutions as promising options for low-energy CO2 release applications.

Abstract

CO 2 captured by amines as bicarbonate is released via PCET. Screening two amines and three modified graphite felts shows MDEA with P-doped felt gives the best interface, speeding CO 2 release and reducing energy demand.
