Two-dimensional carbides and nitrides of early transition metals (MXenes) combine high conductivity with hydrophilic surfaces, which make them promising for energy storage, electrocatalysis, and water desalination. Effects of intercalated metal ions on the vibrational states of water confined in Ti3C2Tx MXenes have been explored using inelastic neutron scattering (INS) and molecular dynamics simulations to better understand the mechanisms that control MXenes’ behavior in aqueous electrolytes, water purification and other important applications. Here, we observe INS signal from water in all samples, pristine and with lithium, sodium or potassium ions intercalated between the 2D Ti3C2Tx layers. However, only a small amount of water is found to reside in Ti3C2Tx intercalated with metal ions. Water in pristine Ti3C2Tx is more disordered, with bulk-like characteristics, in contrast to intercalated Ti3C2Tx, where water is more ordered, irrespective of the metal ions used for intercalation. The ordering of the confined water increases with the ion size. Lastly, this finding is further confirmed from molecular dynamics simulation which showed an increase in interference of water molecules with increasing ion size resulting in a concomitant decrease in water mobility, therefore, providing a guidance to tailor MXene properties for energy and environmental applications.
