Abstract
Modifying MXene surfaces is an effective strategy for controlling interactions with various chemical environments. Here, we demonstrate that treating Ti3C2Tx MXene surfaces with dilute acids and bases results in surfaces enriched with oxygen species capable of reversible proton exchange. These treatments produce surfaces with varying dispersibilities in different organic solvents that can be toggled between “on” and “off” states through successive treatments. Furthermore, we found that protonated MXenes exhibit slower ion kinetics due to surface passivation, whereas deprotonated MXenes show the opposite effect. This research opens avenues toward more versatile solution-based surface modification techniques that may rely less on specific MXene precursors and synthesis methods.
期刊介绍：
ACS Applied Materials & Interfaces is a leading interdisciplinary journal that brings together chemists, engineers, physicists, and biologists to explore the development and utilization of newly-discovered materials and interfacial processes for specific applications. Our journal has experienced remarkable growth since its establishment in 2009, both in terms of the number of articles published and the impact of the research showcased. We are proud to foster a truly global community, with the majority of published articles originating from outside the United States, reflecting the rapid growth of applied research worldwide.
