We’re proud to highlight the excellent work of Xing Li, Charles B. Musgrave III, Andong Liu, Prof. William A. Goddard III, and Prof. Yayuan Liu at Johns Hopkins University. Using Scribner’s inert redox flow cell fixture, the team developed a novel method of capturing CO2 via redox-tunable acid mediated amine regeneration (RAMAR).
Key Highlights:
- Demonstrated stable CO₂ capture–release over 80 cycles (400 h) using readily available N1,N4-diphenylbenzene-1,4-diamine
- Achieved near-unity electrochemical efficiency with ~50% lower theoretical energy consumption
- Showed that N1,N4-diphenylbenzene-1,4-diamine, in the presence of MEA/DMSO, remains redox stable in aerobic conditions and does not mediate O₂ reduction—even with CO₂ present
Why It Matters:
This work showcases a promising, energy-efficient and scalable pathway for carbon sequestration using low-cost, redox-stable amines—paving the way for cleaner, more sustainable energy systems.
Congratulations to the team on this meaningful contribution to the fight against climate change.
