摘要

We report a facile in-situ etching method for the synthesis of defective CuBTC (H-CuBTC) with hierarchical pore structure. The fabricated mixed matrix membranes (MMMs) containing H-CuBTC was prepared for the separation of CO2/CH4, showing superior separation performance due to the defective structure with larger pore size and more open Cu sites, which enhance the interactions between H-CuBTC and the polymer.
