Abstract
Provided is a carbon dioxide recovery system that separates CO2 from a CO2-containing gas containing CO2 by an electrochemical reaction, and comprises an electrochemical cell comprising a working electrode containing a CO2 adsorbent, and a counter electrode. Application of a voltage between the working electrode and the counter electrode causes electrons to be supplied from the counter electrode to the working electrode, and enables the CO2 adsorbent to bind to CO2 as electrons are supplied. The CO2 adsorbent is a crystalline porous body, and has a molecular structure in which a functional group that exchanges electrons and binds to CO2 is regularly arranged.
