Abstract:

With the rapid development of the global economy, the excessive use of fossil energy has led to a large amount of CO₂ emissions, which has aggravated climate change and global greenhouse effect. Carbon capture has become a key means to alleviate environmental pressure. As a class of unique crystalline porous materials, metal organic framework (MOF) possess adjustable structural variability and micro-nano construction functionality. Additionally, various chemical synthesis strategies can be employed to fabricate derivative materials with specific morphology and porosity. MOF and their derivatives have demonstrated exceptional performance and promising application prospects in gas storage, separation, as well as catalytic conversion. In this review, the application of MOF and their derivatives in the field of carbon capture as solid adsorbents, membrane materials and CO₂ desorption catalysts in chemical absorbent solvents was presented. The detailed discussion of their classification, synthesis methods, modification techniques and reaction mechanisms were summarized. The challenges encountered by MOF and their derivative materials in practical applications such as stability, regeneration and large-scale production were thoroughly discussed. Finally, clear pathway for future research investigations was provided. The application of MOF and their derivatives in carbon capture held great potential for offering innovative ideas and solutions to address global carbon emissions issues and contribute to achieving the goal of carbon neutrality.
