Title	Theoretical Investigation of CO₂ Adsorption on Graphene
Author	Kun-Joon Lee, Seung-Joon Kim*
Keywords	DFT, Graphene, CO₂ adsorption, CAM-B3LYP
Abstract	The adsorption of carbon dioxide on graphene sheets was theoretically investigated using density functional theory (DFT) and MP2 calculations. Geometric parameters and adsorption energies were computed at various levels of theory. The CO2 chemisorption energies on graphene-C40 assuming high pressure are predicted to be 71.2-72.1 kcal/mol for the lactone systems depending on various C-O orientations at the UCAM-B3LYP level of theory. Physisorption energies of CO2 on graphene were predicted to be 2.1 and 3.3 kcal/mol, respectively, at the single-point UMP2/6-31G** level of theory for perpendicular and parallel orientations.
