Membrane technology has been recognized as an attractive and environment-friendly technology for the gas separation due to its low energy consumption, easy operation, and cost. Covalent organic frameworks (COFs) and their mixed-matrix membranes (MMMs) are the emerging candidates for the gas separation owing to their designable porosity and functionality. Modification and rational synthesis of COFs with variable metal ions and organic linker helps to adjust molecular sieving via tunable pore size, shape, defects, and surface functionalities. COFs based MMMs characterized by FTIR, TGA, XRD, BET surface area, and pore size analysis. The membrane selectivity, permeability, and stability for the H2 and CH4 over H2/CH4 mixture were investigated. The gaseous products (H2 and CH4) analyzed using GC-FID. |
