Abstract
A method of desorbing CO2 from an aqueous liquid comprising CO2, the method comprising the steps of: a) providing said aqueous liquid in the form of an aqueous colloidal solution comprising (i) a CO2 absorbent having CO2 absorbed thereto and (ii) colloidal catalyst having a core-shell structure in which the shell comprises proton-donor groups, and b) thermally desorbing CO2 from the CO2 absorbent, wherein the thermal desorption of the CO2 is catalysed by the colloidal catalyst.
