Photocatalytic technology has received increasing attention in recent years. A pivotal facet of photocatalytic technology lies in the development of photocatalysts. Porous metal-organic framework (MOF) materials, distinguished by their unique properties and structural characteristics, have emerged as a focal point of research in the field, finding widespread application in the photo-treatment and conversion of various substances. Fe-based MOFs have attained particular prominence. This review explores recent advances in the photocatalytic degradation of aqueous and gaseous substances. Furthermore, it delves into the interaction between the active sites of Fe-MOFs and pollutants, offering deeper insights into their mechanism of action. Fe-MOFs, as photocatalysts, predominantly facilitate pollutant removal through redox processes, interaction with acid sites, the formation of complexes with composite metal elements, binding to unsaturated metal ligands (CUSs), and hydrogen bonding to modulate their respiratory behavior. This review also highlights the focal points of future research, elucidating the challenges and opportunities that lie ahead in harnessing the characteristics and advantages of Fe-MOF composite catalysts. In essence, this review provides a comprehensive summary of research progress on Fe-MOF-based catalysts, aiming to serve as a guiding reference for other catalytic processes.
近年来，光催化技术受到了越来越多的关注。光催化技术的一个关键方面在于光催化剂的开发。多孔金属有机框架（MOF）材料以其独特的性质和结构特征而著称，已成为该领域的研究热点，在各种物质的光处理和转化中得到广泛应用。铁基金属有机框架（Fe-MOFs）尤为突出。本文综述了光催化降解水性和气态物质的最新进展。此外，还深入探讨了Fe-MOFs活性位点与污染物之间的相互作用，对其作用机制有了更深入的了解。作为光催化剂，Fe-MOFs主要通过氧化还原过程、与酸性位点的相互作用、与复合金属元素形成络合物、与不饱和金属配体（CUSs）结合以及氢键作用来调节其呼吸行为，从而促进污染物的去除。本文还强调了未来研究的重点，阐明了利用Fe-MOF复合催化剂的特性和优势所面临的挑战和机遇。本质上，本文全面总结了基于Fe-MOF的催化剂的研究进展，旨在为其他催化过程提供指导参考。
