Balancing the Crystallinity and Film Formation of Metal–Organic Framework Membranes through In Situ Modulation for Efficient Gas Separation

Angewandte Chemie International Edition, Год журнала: 2023, Номер 62(37)

Опубликована: Июль 25, 2023

Polycrystalline metal-organic framework (MOF) layers hold great promise as molecular sieve membranes for efficient gas separation. Nevertheless, the high crystallinity tends to cause inter-crystalline defects/cracks in nearby crystals, which makes crystalline porous materials face a challenge fabrication of defect-free membranes. Herein, first time, we demonstrate balance between and film formation MOF membrane through facile situ modulation strategy. Monocarboxylic acid was introduced modulator regulate via competitive complexation thus concomitantly control film-forming state during growth. Through adjusting ratio acid/linker acid, an appropriate this structural "trade-off" achieved. The resulting with moderate coherent morphology exhibits sieving H2 /CO2 separation selectivity up 82.5.
