Project

Poly(propylenimine) Sorbents for CO2 Capture from Ambient Air

I work on development and understanding of silica-supported poly(propylenimine) (PPI) sorbents for CO2 capture from ambient air. We have demonstrated that PPI-based sorbents are as efficient as or better than the traditionally-used poly(ethylenimine)- (PEI-) based sorbents for adsorption of CO2 nd have additionally discovered that PPI is more resistant to oxidation than PEI. This is allows sorbents based on PPI to be less sensitive to the presence of oxygen during regeneration, allowing for longer sorbent working lifetimes. We are working on understanding the nature of this stability and designing materials around the use of PPI.
