Efficient CO/CH Separation Using Polysulfone/NH-MIL-125(Ti) Mixed Matrix Membranes.

This study investigates the fabrication and optimization of mixed matrix membranes (MMMs) composed of NH-MIL-125(Ti), a metal-organic framework (MOF), dispersed within a polysulfone (PSf) polymer matrix, for efficient CO/CH separation. The MMMs were prepared by using a solution casting method, and their morphology and gas separation performance were systematically characterized. The effect of MOF addition into the polymer matrix, gas permeability, and selectivity were evaluated using a gas permeation setup.
