Metal-organic frameworks (MOFs) represent a category of crystalline materials formed by the combination of metal ions or clusters with organic linkers, which have emerged as a prominent research focus in the field of photocatalysis. Owing to their distinctive characteristics, including structural diversity and configurations, significant porosity, and an extensive specific surface area, they provide a flexible foundation for various potential applications in photocatalysis. In recent years, researchers have tackled many issues in the MOF-based photocatalytic yield. However, limited light adsorption regions, lack of active sites and active species, and insufficient efficiency of photogenerated charge carrier separation substantially hinder the photocatalytic performance. In this review, we summarized the strategies to improve the photocatalytic performance and recent developments achieved in MOF and MOF-based photocatalysis, including water splitting, CO conversion, photocatalytic degradation of pollutants, and photocatalytic nitrogen fixation into ammonia. In conclusion, the existing challenges and prospective advancements in MOF-based photocatalysis are also discussed.
金属有机框架材料(MOFs)是一类由金属离子或簇与有机连接体结合形成的晶体材料,已成为光催化领域的一个重要研究热点。由于其独特的特性,包括结构多样性和构型、显著的孔隙率以及较大的比表面积,它们为光催化中的各种潜在应用提供了一个灵活的基础。近年来,研究人员已经解决了基于MOF的光催化产率中的许多问题。然而,有限的光吸收区域、活性位点和活性物种的缺乏以及光生载流子分离效率不足,严重阻碍了光催化性能。在这篇综述中,我们总结了提高光催化性能的策略以及在MOF和基于MOF的光催化方面取得的最新进展,包括水分解、CO转化、污染物的光催化降解以及光催化固氮制氨。总之,还讨论了基于MOF的光催化中存在的挑战和未来的进展。
