Abstract：

Metal-organic frameworks are widely used for separation applications due to its large porosity, high specific surface area and tunable pore size. Heteropoly acid is a kind of ideal material for proton transfer and storage because of its large molecular radius, strong hydrophilicity and super acidity. In this context, we report a facile one-pot solvothermal synthesis strategy to fabricate a series new nanocomposites by filling different content of phosphotungstic acid (HPW) in the cavity of MIL-101 (HPW@MIL-101). We further immobilized HPW@ MIL-101 nanocomposites in SPPO/PVA composite membranes to fabricate the mixed matrix membranes. The stability and dispersion of HPW@MIL-101 in SPVA were investigated. In addition, the effects of HPW@MIL-101 with different content of HPW on H+ transport and H+/Fe2+ separation properties were systematically discussed. Specifically, with the increase of HPW content, the ion permeation fluxes of H+ and H+/Fe2+ permselectivity obviously increased. The resulting representative HWS-3 membrane offers excellent H+ permeation (1.27 10-6 mol/(cm2·s) )and impressive H+/Fe2+ selectivity (＞210).
