GasSeparationsUtilizingPorousOrganicStructures:Advances andPerspectives

Abstract
The pressing global challenge of energy-intensive industrial separation processes necessitates innovative, efficient, and sustain\r\nable alternatives. Porous organic solids(POSs) have emerged as a\r\n transformative class of materials, offering remarkable properties\r\n suchashighsurfacearea, tunableporestructures,andchemical\r\n versatility forgas separationapplications. This reviewprovides\r\n adetailedoverviewof recentadvancements inthedesign, syn\r\nthesis,andapplicationofPOSs,encompassingcovalentorganic\r\n frameworks (COFs), conjugatedmicroporouspolymers (CMPs),\r\n polymers of intrinsic microporosity (PIMs), porous aromatic\r\n frameworks (PAFs), andhypercrosslinkedpolymers (HCPs).Key\r\n mechanisms, includingmolecular sieving, facilitated transport,\r\n andsolution-diffusion, areexamined toelucidate the rolesof\r\n POSsinachievingselectiveandenergy-efficientgasseparations.\r\n TheintegrationofPOSs inmixed-matrixmembranes(MMMs) is\r\n highlightedasapromisingstrategy for enhancingtheir scala\r\nbilityandindustrial applicability.Challengessuchasscalability,\r\n long-termstability,andcompatibilityinMMMsarecriticallyana\r\nlyzedalongsiderecentadvancementsaddressingthesebarriers.\r\n Future directions emphasize the development of POSs with\r\n enhanced functionalization, structural stability, and innovative\r\n composite formulations tomeet thegrowingdemandfor sus\r\ntainableindustrialgasseparationtechnologies.Thisreviewaims\r\n toprovideacomprehensiveresourceforresearchersandindus\r\ntryprofessionals, bridging fundamental sciencewithpractical\r\n applications.
