Abstract

In response to global clean energy demands, this study develops mixed matrix membranes (MMMs) for gas separation in renewable energy applications. MMMs are produced through phase inversion by employing polysulfone and bimetallic-ZIF (Ni–Co-ZIF-67). Bimetallic-ZIF, formed in-situ by Co and Ni metals in water solvent with triethylamine, enhances gas selectivity. MMMs with 4 wt% bimetallic-ZIF, Co: Ni ratio of 9:1 (4Ni10Z67), exhibit remarkable selectivity: CO2/CH4 (21.19), H2/N2 (1.47), H2/CH4 (44.82), and N2/CH4 (30.40). Strong interactions between bimetallic-ZIF and CO2, facilitated by molecular sieving and Ni–Co sites, contribute to these results.
