Abstract Membrane processes are promising for energy‐saving industrial applications.

The purpose of this study was to design and develop a self-supporting glass MOF membrane (GMM) including its design, fabrication under different heat treatment temperatures, analysis physical–chemical properties, assessment separation performance. Glass MOFs preserve metal–ligand bonding structures similar their crystalline counterparts, providing intrinsic gas properties alongside the benefits amorphous materials, reduced grain boundaries ease processing. In work, ZIF-62 melted then cooled fabricate GMMs using vitrification enhance molecular sieving. This systematically examines impact varying thermal temperatures (400–475 °C) on physical chemical transformations GMMs, revealing effects porosity, defect formation, sieving performance through advanced characterization techniques (e.g., solid-state nuclear magnetic resonance (13C NMR), X-ray photoelectron spectroscopy (XPS), He pycnometry, positron annihilation lifetime (PALS)). optimal GMM exhibits an impressive performance, particularly for H2 separation. at 4 bar 25 °C exhibited He, H2, CO2, N2, CH4 permeations 576.37, 509.23, 146.07, 3.45, 2.28 barrer, respectively. ideal selectivities H2/CH4, CO2/N2, CO2/CH4, H2/N2, H2/CO2 pairs were 223.47, 42.37, 64.10, 147.71, 3.49, respectively, which significantly exceed earlier reported values membranes, demonstrating significant potential as high-performance sieve work by optimizing process systematic temperature control highlights GMM's ability achieve high selectivity permeability, positioning it promising candidate industrial applications.
