Abstract:
An adsorbent for carbon dioxide may include a composite metal oxide including a divalent first metal (M1), a trivalent second metal (M2), and at least one polyoxometalate (POM) ion selected from an anion represented by a first formula (e.g., Chemical Formula 1) and an anion represented by a second formula (e.g., Chemical Formula 2). A capture module for carbon dioxide may include the adsorbent.
