To address this, dispersing metal atoms as single sites on a substrate can utilize their highly localized electronic structure and concentrated charge to enhance polarization of noble gas atoms, thereby achieving effective Xe\/Kr adsorption and separation. Two\u2010dimensional MXene materials, with their large specific surface areas and tunable surface terminal groups, offer promising substrates for supporting metal atoms. In this study, we performed ab initio density functional theory (DFT) calculations to systematically evaluate the adsorption and separation capabilities of transition metal (TM) functionalized Ti\n                    <jats:sub>3<\/jats:sub>\n                    C\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    (TM\u2010Ti\n                    <jats:sub>3<\/jats:sub>\n                    C\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    ) for Xe and Kr.
