Carbon dioxide adsorbent including barium titanate, carbon dioxide capture module including the same, and methods for separating carbon dioxide using the same

摘要

A carbon dioxide adsorbent may include a complex oxide including barium and titanium, wherein the complex oxide has a perovskite crystalline structure and is represented by the general formula Ba_xTi_yO_z, and an atomic ratio of Ba/Ti ranges from about 0.95 to about 1.7. The carbon dioxide adsorbent may be included in a carbon dioxide capture module. The carbon dioxide adsorbent may also be used in a method of separating carbon dioxide.
