SERS Raman detection of the CO$_2$ Moisture Swing (opens in new tab)

The development of scalable, energy-efficient carbon dioxide capture technologies is critical for achieving net-zero emissions. Moisture swing sorbents offer a promising alternative to traditional thermal regeneration methods by enabling reversible CO$_2$ binding through humidity-driven ion hydrolysis. In this study, we investigate the anion speciation dynamics in two classes of MS materials, an anion-exchange resin with bicarbonate anion an...
