Examining interfacial interactions in metal-organic framework glass composites to enhance gas separation performance (2026)
Abstract
Metal-organic framework glass composites are promising materials for gas separation membranes. We have previously observed that incorporation of graphitic-C3N4 into a ZIF-62 glass enhances gas separation performance and improves the mechanical properties of the membrane, however the precise mechanisms for these improvements remain unclear. In this project, we will use XAS to probe the local electronic structure and coordination environment of zinc ions in the glass to better understand the role of interfacial coordination between the zinc and nitrogen-rich g-C3N4 sites. This will promote development of environment-sensitive interfacial models and guide the design of advanced multifunctional materials for gas separations.
