Donated industrial CO₂ sorbents Na₂O/Al₂O₃ were studied by means of DRIFTS and Raman spectroscopy, along with X% Na₂O/Al₂O₃ sorbents synthesized by incipient wetness impregnation. CO₂ adsorption studies revealed multiple adsorbed carbonate species. The role of adsorbed carbonate species in the reversible CO₂ capture process will be discussed.
