Metal-organic framework (MOF) glass is a versatile and processible material that retains its porous nature while transitioning between liquid and solid states. Incorporating composites into MOF glass can enhance its functionalities, but the effect on its state conversion remains understudied. This research explores the impact of silver ions on the properties of ZIF-62 glass, revealing their influence on phase conversion at varying ligand concentrations. The presence of silver enhances gas separation processes, particularly improving CO2 and hydrocarbon separation selectivity compared to pure ZIF-62 glass. These findings provide valuable insights for composite integration and highlight the potential of Ag-doped ZIF-62 glass in gas separation applications. Furthermore, this work paves the way for processing functional Ag-doped ZIF-62 glass films, enabling diverse applications such as gas separation, film catalysis, and antimicrobial glass.
