In the fabrication of zeolitic imidazolate frameworks (ZIFs) thin films and membranes, the preparation of stable ZIFs dispersions is crucial. Herein, ultra-stable ZIF-8 aqueous dispersions were obtained successfully for the first time. It was found that, after the synthesis of ZIF-8, with the increased washing times, the positive surface potentials of ZIF-8 particles decrease, resulting in increased...

Supported inorganic membranes hold the promise of highly effective separation and purification, and stable operation in harsh environments. Examples are thin films of paladium alloy for H2, mixed conducting oxides for O2, amorphous silica for CO2 and zeolites for hydro-carbons, and meso-porous titania for water purification. However, compared to organic membranes, large-scale production of inorganic...
