Frontispiece: Zinc Coordination-Polymer-Mediated Self-Assembly of Nanoparticles into “Brick-and-Mortar” Membranes for Hydrogen Separation

Abstract

A nacre-inspired composite membrane with “brick-and-mortar” structure is reported by Jürgen Caro, Heqing Jiang et al. in their Communication (e202416919). Dominant “brick” microporous zeolitic imidazolate framework nanoparticles allow fast H₂ transport, while the “mortar” coordination polymer interlayer combined with an adhesive interface reduces the intercrystalline transport and provides a highly H₂ selective transport pathway, resulting in an exceptional H₂/CO₂ separation performance.
