Advanced Strategies in Metal-Organic Frameworks for CO Capture and Separation

The continuous carbon dioxide (CO ) gas emissions associated with fossil fuel production, valorization, and utilization are serious challenges to the global environment. Therefore, several developments of CO capture, separation, transportation, storage, and valorization have been explored. Consequently, we documented a comprehensive review of the most advanced strategies adopted in metal-organic frameworks (MOFs) for CO capture and separation. The enhancements in CO capture and separation are generally achieved due to the chemistry of MOFs by controlling pore window, pore size, open-metal sites, acidity, chemical doping, post or pre-synthetic modifications. The chemistry of defects engineering, breathing in MOFs, functionalization in MOFs, hydrophobicity, and topology are the salient advanced strategies, recently reported in MOFs for CO capture and separation. Therefore, this review summarizes MOF materials' advancement explaining different strategies and their role in the CO mitigations. The study also provided useful insights into key areas for further investigations.
