Proton coupled electron transfer mechanism in low-energy electrochemical CO 2 desorption from Tiron-mediated amine solutions

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.
