Abstract
Provided are a carbon dioxide absorbent including an ionic liquid including a choline-based cation and a phenolate-based anion, and an aliphatic alcohol, and a method of separating carbon dioxide using the same. Since the carbon dioxide absorbent of the present disclosure is thermally and chemically stable, it may decrease by-products released into the atmosphere and thus, is environmentally friendly. The method of separating carbon dioxide using the absorbent is an economical method which allows energy saving with low renewable energy.
