Facilitated transport membrane for carbon capture applications.
Facilitated transport membrane for carbon capture applications.
Reduction of carbon dioxide at the point of its generation is a key to combat global warming and climate change. Electricity generation sector, accounting for more than 25% of carbon emission, provides an unique opportunity to separate out gaseous carbon dioxide from its mixture with nitrogen. Facilitated transport membranes can overcome the selectivity-permeability trade-off by having reversible fast reaction with mobile moieties within the membrane and the carbon dioxide molecule. However these membrane suffers from instability and we develop an unique way to stabilize the mobile moieties using charge-charge interactions.Â
