Nanoconfinement enabled non-covalently decorated MXene membranes for ion-sieving

Yuan Kang et al.

Summary: The authors demonstrate controllable and selective mass transport through non-disruptive non-covalent modification of sub-1-nm MXene channels, enabled by nanoconfinement effect. Traditional covalent modification used to tune the size and functionality of 2D membranes often disrupts the membrane structure. However, in this study, non-intrusive non-covalent modifications on Ti3C2Tx MXene membranes were achieved by solvent treatment, resulting in densely functionalized channels decorated by protic solvents via hydrogen bond network. These as-decorated membranes exhibit stable ion rejection and enhanced proton-cation selectivity, making non-covalent methods a potential modification alternative for nanochannels in energy, resource, and environment-related applications.
