Abstract The rapid development of new energy industry is leading to the scarcity lithium (Li) metal. Rational design adsorbents for efficient separation Li + ion from aqueous media pivotal solve recovery this valuable resource. Current generally suffer drawbacks in adsorption capacity, kinetics, and selectivity. Herein, a novel ultra‐stable metal–organic framework designed separation. dense oxygen atoms on cambered wall its 1D channel encircle form angstrom‐level tetrahedral pockets array, acting as dominant sites. This rational distribution array avoids pore blockage caused by pre‐adsorbed ions, thereby accelerating diffusion subsequent ions into interior pore. Meanwhile, pocket shows distinct electronegativity strong chelation effect . Benefiting these specifics, adsorbent exhibits record‐breaking capacity (76.1 mg g −1 ) short equilibrium time (30 min). Moreover, selective over Na , K Ca 2+ Mg achieved due matched diameter with pocket/channel sizes lower barrier dehydration. Thus, work proposes feasible strategy construction MOFs adsorption.

A novel imprinted porous liquid for lithium extraction

AIChE Journal, Journal Year: 2024, Volume and Issue: 70(12)

Published: Aug. 28, 2024

Abstract Porous liquids (PLs) are a novel material that combines the advantages of porous solids and liquid fluidity. In this study, we propose an imprinted (IPL) with polymers as framework mixture TOP + FeCl 3 sterically hindered solvents. Quantum chemical computations characterization results demonstrate presence unoccupied pore structure in IPLs. The prepared IPLs exhibit excellent selective adsorption extraction performance for lithium extraction, achieving Li/Mg separation factor 1540 single‐stage Li efficiency 86%. remains above 84% even after eight cycles. Analytical along quantum elucidates mechanism underlying coupling between IPLs, enabling efficient extraction. By combining imprinting technology PLs, expand upon existing frameworks PLs materials while providing new insights designing functional
