Abstract

This study investigates novel thin-film nanocomposite (TFN) membranes for enhanced CO₂/CH₄ separation. A layered double hydroxide@metal–organic framework (LDH@MOF) hybrid filler is incorporated into a PEBAX-based selective layer on a polysulfone (PSf) substrate. The results show that the LDH@MOF filler, LM-0.1, fully covers the MOF and TFN-0.1 also shows promising performance with 11GPU CO₂ permeance, and 20 CO₂/CH₄ selectivity with improvement to 95 %. This work highlights the potential of LDH@MOF hybrid fillers for surpassing limitations of single fillers and polymeric membranes in gas separation applications, suggesting a practical approach for biogas upgrading.

在 PEBAX 薄膜纳米复合膜中加入 LDH@MOF 混合填料，实现定制气体分离并提高 CO2/CH4 选择性

本研究探讨了用于增强 CO2/CH4 分离的新型薄膜纳米复合材料（TFN）膜。在聚砜（PSf）基底上的基于 PEBAX 的选择层中加入了层状双氢氧化物@金属有机框架（LDH@MOF）混合填料。结果表明，LDH@MOF 填料 LM-0.1 完全覆盖了 MOF，TFN-0.1 也显示出良好的性能，二氧化碳渗透率达到 11GPU，二氧化碳/CH4 选择性达到 20%，并提高到 95%。这项工作凸显了 LDH@MOF 混合填料在气体分离应用中超越单一填料和聚合物膜的局限性的潜力，为沼气升级提供了一种实用的方法。
