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.
