Metal–organic frameworks (MOFs) are some of the most interesting and promising candidates to sequester toxic H₂S and SO₂ gases. MOFs show interesting advantages over classic porous materials due to their chemical composition, ligand functionality, cavity dimensions, ease of preparation, and relatively low cost reactivation. The optimization of the physical–chemical interactions between MOFs and H₂S and SO₂ molecules is the key to further amplification of their capture. Reversibility after the adsorption of H₂S and SO₂ can be modulated through noncovalent bonding between functionalized ligands (within MOF structures) and H₂S and SO₂. This review aims to summarize recent advances in the development of MOF-based systems for the capture and removal of H₂S and SO₂. We anticipate that this review article can offer very useful information on the significant and rapid progress of the enhancement of H₂S and SO₂ capture by MOFs.

用于捕获高毒性H ₂ S和SO _2的MOF材料

金属有机框架（MOF）是隔离有毒H ₂ S和SO ₂气体的最有趣和最有前途的候选者。与传统的多孔材料相比，MOF由于其化学成分，配体官能度，空腔尺寸，易于制备以及相对较低的成本活化而显示出有趣的优势。MOF与H ₂ S和SO ₂分子之间的物理化学相互作用的优化是进一步扩大其捕获量的关键。H ₂ S和SO ₂吸附后的可逆性可以通过功能化配体（在MOF结构内）与H ₂ S和SO ₂之间的非共价键调节。这篇综述旨在总结基于MOF的系统的最新进展，该系统用于捕获和去除H ₂ S和SO ₂。我们希望这篇评论文章可以提供有关MOF增强H ₂ S和SO ₂捕获的显着快速进展的非常有用的信息。
