In this study, a cost-effective modified pore-optimized MOF-808 was developed and used to fabricate high-performance CO2 capture mixed matrix composite membranes (MMCMs). The prepared MMCM showed remarkable CO2 permeance and selectivity, demonstrating potential applications in various gas purification fields.
Mixed matrix composite membranes (MMCMs) are considered as one of the potential directions for the develop-ment of CO2 capture membranes. Nevertheless, the high cost and the challenging nature of improving separation performance are significant obstacles that prevent MMCMs from being widely applied in practice. In this study, we developed a cost-effective modified pore-optimized MOF-808 (MOF-808@PVAm) and utilized it to fabricate high-performance CO2 capture MMCMs. Specifically, MOF-808 and polyvinylamine (PVAm) were cross-linked by ������-(2,3-epoxypropoxy) propytrimethoxysilane (KH-560), which improved the pore structure characteristics of MOF-808 and led to high-performance MMCMs. For 2 bar feed gas (CO2/N2, 15/85), the MMCM with 33.33 wt.% MOF-808@PVAm loading displayed remarkable CO2 permeance of 2753 GPU and selectivity of 181. The prepared MMCM demonstrated good operational stability in simulated flue gas and exhibited potential for application in various gas purification fields (CO2 /CH4, CO2/H2) through gas permeation tests.
