Biological Metal-Organic Framework Materials for CO2 Capture Performance
Efficient capture and selective separation of CO2 is one of the important means to realize the “dual carbon” goal and mitigate climate change, and metal-organic frameworks (MOFs) show great potential in gas separation and storage due to their structural peculiarities. The potential of MOFs in the field of gas separation and storage is enormous. Among them, biological metal-organic framework (Bio-MOFs) are constructed by green synthesis pathway using natural biomolecules (e.g., amino acids, nucleobases, peptides, etc.) as ligands, and they are both environmentally friendly and cost-effective, providing innovative solutions for CO2 capture. This paper will focus on the following: systematically summarizing the structural properties of the bio-ligands and their modulation of the framework pores and chemical properties; exploring the mechanism of direct synthesis and post-synthesis modification (e.g., amine functionalization, ion exchange) and other strategies to enhance the performance of the materials; analyzing the adsorption behaviors of the Bio-MOFs of CO2 in complex media, elucidating the synergistic roles of molecular sieving, equilibrium sieving, and gating effects; and analyzing the CO2 adsorption behaviors of the Bio-MOFs in complex media, synergistic effect; and the challenges and future development direction of Bio-MOFs are also prospected.
