Interface-enhanced CO₂ capture via the synthetic effects of a nanomaterial-supported ionic liquid thin film.

ABSTRACT: Ionic liquids (ILs) are effective CO₂ capture media and recent experimental evidence has demonstrated that the addition of two-dimensional (2D) nanomaterials into ILs can effectively improve their CO₂ capturing capability. However, an in-depth mechanism on how 2D nanomaterials enhance CO₂ absorption is poorly documented. In this study, the adsorption of CO₂ by a representative IL, namely 1-ethyl-3-methyl-imidazole-tetrafluoroborate ([EMIM][BF₄]), coated on graphene (GRA, the prototype 2D nanomaterial) and nitrogenized graphene (C₃N) was investigated by molecular dynamics simulations. The influence of the IL film thickness on the amount of CO₂ adsorption was systematically analyzed. Our data clearly indicate that a
