Proton Redox and Transport in MXene-Confined Water
TL;DR: This work uses first-principles molecular dynamics simulations to reveal the proton-transfer mechanism in MXene-confined water layers of different thicknesses by using O-terminated Ti3C2 as a prototypical MXene, and finds that theProton redox process takes place reversibly between surface -O sites and interfacial water molecules, intermitted by the more frequent in-water proton transfer events.
