A carbon dioxide recovery system, which is configured to separate and recover carbon dioxide from a carbon dioxide containing gas, includes an adsorption unit that includes an adsorbent material that is configured to adsorb and desorb the carbon dioxide. The adsorbent material is configured to radiate heat in response to adsorption of the carbon dioxide and is configured to absorb the heat in response to desorption of the carbon dioxide. The adsorption unit is one of a plurality of adsorption units, and adjacent two adsorption units among the plurality of adsorption units contact with each other. When one of the adjacent two adsorption units adsorbs the carbon dioxide, another one of the adjacent two adsorption units desorbs the carbon dioxide.

Provided is the use of a carboxylate compound as an absorbent for capturing carbon dioxide and/or in the preparation of an absorbent for capturing carbon dioxide.
