【 摘 要 】

ts The zeolitic imidazolate framework functionalized modified layered double hydroxide (ZIF-8@MLDH) composite membranes with superior structural stability and Li+ permeability are prepared by selectively growing ZIF-8 nanoparticles in the framework defects of the MLDH membrane.The tailor-made ZIF-8@MLDH membrane has a large Li+ permeability of up to 1.73 mol m-2 h-1 and a high Li+/Mg2+ selectivity of 31.9, which exceed most of the current 2D lamellar membranes.
