Transformation of Al-CDC from 3D crystals to 2D nanosheets in macroporous polyacrylates with enhanced CH4/N2 separation efficiency and stability

Development of materials with high efficiency and long-life cycles for CH4/N2 separation is of importance for coal-bed methane purification. Herein, a composite was prepared by in-situ growing the specific aluminum-based metal–organic framework (MOF) with trans-1,4-cyclohexanedicarboxylicacid as ligand (Al-CDC) on the internal macroporous surface of polyacrylates (PA). Due to the surface-induced low-energy-barrier orientation crystallization,...
