Simultaneous voltage-gated control of ion and water transport in Zr₄-Ti₃C₂T_x nanochannel membranes.

ABSTRACT: Controlling water and ion transport across nanoconfined channels is essential for natural biological processes and crucial for breakthroughs in diverse scientific and technological fields. Here, we present an efficient voltage-controlled strategy that simultaneously regulates water and ion diffusion by fine-tuning the external voltage applied to a high-conductivity Zr₄-Ti₃C₂T_x nanochannel membrane, which demonstrates high structural stability in aqueous environments. Under positive voltage, ion permeation increased by a factor of 10.18, whereas negative voltage reduced it to 0.17 of its original value. Interestingly, water diffusion exhibited the opposite response, with negative voltage enhancing water transport due to the facilitated rotation mo
