摘要

Membranes for hydrogen-carbon dioxide (H-2-CO2) gas separation have potential applications as energy-efficient components in carbon capture technology. Mixed-matrix membranes (MMMs), which are composed of polymers and filler materials such as metal-organic frameworks (MOFs), are used to achieve a good separation performance by leveraging the intrinsic benefits of each component. However, developing robust interfacial compatibility between polymers and filler materials is a critical challenge. On page 1350 of this issue, Chen et al. (1) report a solid-solvent processing (SSP) strategy to fabricate defect-free MOF-based MMMs with ultrathin selective layers and high filler loadings that are capable of separating gas pairs with subangstrom precision.
