Extracting lithium from salt lakes requires ion-selective membranes with customizable nanochannels. However, it remains a major challenge to separate alkali cations due their same valences and similar ionic radius. Inspired by the K+ channel of KcsA K+, significant progress has been made in adjusting nanochannel size control ion selectivity dominated dehydration. Besides, several works involved incorporating ligands, such as crown ether, into nanochannels based on coordination chemistry try promote cation selectivity; nevertheless, only separation between mono-/bivalent achieved. Herein, series heteropolyacid (HPA) ligands are designed functionalize two-dimensional (2D) nanochannels, achieving superior perm-selectivity over other (16 for Li+/K+), Li+ permeation rate increased four times that pristine 2D membrane. We discover switching an its hydration ion-HPA states elucidates transport, relatively lower depth energy well exchange Li+-HPA results cations. This work demonstrates principle exploring novel develop cation-selective membranes, expanding potential applications extraction aquatic sources.
