Due　to　the　greenhouse　effect　caused　by　carbon　dioxide　(CO2)　emission,　much　attention　has　been　paid　for　the　removal　of　CO2.　Porous　liquids　(PLs),　as　new　type　of　liquid　materials,　have　obvious　advantages　in　mass　and　heat　transfer,　which　are　widely　used　in　gas　adsorption　and　separation.　Metal–organic　frameworks　(MOFs)　with　the　merit　like　large　surface　area,　inherent　porous　structure　and　adjustable　topology　have　been　considered　as　one　of　the　best　candidates　for　PLs　construction.　This　review　presents　the　state-of-the-art　status　on　the　fabrication　strategy　of　MOFs-based　PLs　and　their　CO2　absorption　and　utilization　performance,　and　the　positive　effects　of　porosity　and　functional　modification　on　the　absorption-desorption　property,　selectivity　of　target　product,　and　regeneration　ability　are　well　summarized.　Finally,　the　challenges　and　prospects　for　MOFs-based　PLs　in　the　optimization　of　preparation,　the　coupling　of　multiple　removal　techniques,　the　in　situ　characterization　methods,　the　regeneration　and　cycle　stability,　the　environmental　impact　as　well　as　expansion　of　application　are　proposed.　©　2025　Institute　of　Process　Engineering,　Chinese　Academy　of　Sciences
