An adsorbent for carbon dioxide may include a composite metal oxide including a divalent first metal (M), a trivalent second metal (M), 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. 1. An adsorbent for carbon dioxide , comprising:{'sup': 1', '2, 'claim-text': {'br': None, 'sup': 3', '2−, 'sub': 6', '19, '[MO]\u2003\u2003[Chemical Formula 1]'}, 'a composite metal oxide including a divalent first metal (M), a trivalent second metal (M), and at least one polyoxometalate (POM) ion, the at least one polyoxometalate (POM) ion selected from an anion represented by Chemical Formula 1 and an anion represented by Chemical Formula 2,'}{'sup': '3', 'claim-text': {'br': None, 'sub': 4', 'a', '6b', '18b, 'sup': 4', '3a−, '[(XO)MO]\u2003\u2003[Chemical Formula 2]'}, 'Mbeing selected from at least one of Mo and W,'}X being selected from at least one of P, Si, As, Ge, B, Co, and Zn,{'sup': '4', 'Mbeing selected from at least one of Mo, W, and V,'}a being in a range of about 1 to about 5, andb being in a range of about 2 to about 5.2. The adsorbent for carbon dioxide of claim 1 , wherein Chemical Formula 2 is further represented by at least one of Chemical Formula 2A claim 1 , Chemical Formula 2B claim 1 , and Chemical Formula 2C claim 1 ,{'br': None, 'sub': 4', 'l', '12−l', '36, 'sup': '3−', '[(XO)MoWO]\u2003\u2003[Chemical Formula 2A]'} {'br': None, 'sub': 4', '12−m', 'm', '36, 'sup': '(3+m)−', '[(XO)MoVO]\u2003\u2003[Chemical Formula 2B]'}, 'l being in a range of about 0 to about 12,'} {'br': None, 'sub': 4', '12−n', 'n', '36, 'sup': '(3+n)−', '[(XO)WVO]\u2003\u2003[Chemical Formula 2C]'}, 'm being in a range of about 0 to about 3,'}n being in a range of about 0 to about 3.3.
