Metal–organic framework (MOF) membranes with high ion selectivity are highly desirable for direct lithium-ion (Li+) separation from industrial brines. However, very few MOF can efficiently separate Li+ brines of Mg2+/Li+ concentration ratios and keep stable in ultrahigh Mg2+-concentrated This work reports a type MOF-channel (MOFCMs) by growing UiO-66-(SH)2 into the nanochannels polymer substrates to improve efficiency challenging extraction. The resulting demonstrate excellent monovalent metal over divalent ions, Li+/Mg2+ up 103 since Mg2+ should overcome higher energy barrier than when transported through pores, as confirmed molecular dynamics simulations.

ConspectusThe smart regulation of ion flow in biological channels (BICs) is vital to life. In general, intelligent BICs possess three main functions: (i) selectively transfer specific ions, (ii) quickly conduct and (iii) responsively control the ions. Since early exploration potassium (K+) sodium (Na+) began 1950s, gating behaviors have been investigated for more than 70 years. Taking first reported voltage-gated transport process as an example, a gate, which acts voltage sensor BICs, detects variation membrane voltage, triggering opening closing channels. A ratio (GR) can describe effect BIC, GR = IOpen/IClosed, where IOpen IClosed are measured currents channel at open closed states, respectively. usually strong effects with extraordinarily high ratio, be up infinity zero-current states. Inspired by nature, artificial (AICs) constructed permeation intelligently. 2004, wide range AICs developed regulate ions via external stimulation (i.e., light, pH, magnetic field, temperature).
