Harnessing solar energy through photocatalysis has excellent potential for powering sustainable chemical production, supporting the United Nations' environmental goals. Single-atoms (SAs) dispersed on catalyst surfaces are gaining attention for their highly active and durable nature. Metal-organic frameworks (MOFs) can provide enough reactive sites to sustain selectivity and durability over time because of their tunable channels and functional groups. Owing to their organized structures, MOFs are ideal platforms for securing individual atoms and promoting solar-driven reactions. Few reviews have, however, reflected the possibility of combining MOFs and SAs to produce potent photocatalysts that may produce clean fuels and valuable chemicals. This review provides a general overview of methods for combining MOFs and SAs to generate photocatalysts. The challenges associated with these MOF-based single-atom systems are also critically examined. Their future development is discussed as continued refinement helps to more fully leverage their advantages for boosting photocatalytic performances - turning sunlight into chemicals in a manner that supports sustainable development. Insights gained here could illuminate pathways toward realizing the profound potential of MOF-based single-atom photocatalysts to empower production driven by renewable solar energy.
通过光催化利用太阳能在推动可持续化学生产方面具有巨大潜力，有助于实现联合国的环境目标。分散在催化剂表面的单原子因其高活性和耐久性而备受关注。金属有机框架（MOF）因其可调节的通道和官能团，能够提供足够的反应位点以长期维持选择性和耐久性。由于其有序的结构，MOF是固定单个原子和促进太阳能驱动反应的理想平台。然而，很少有综述反映出将MOF和单原子结合以制备可能生产清洁燃料和有价值化学品的高效光催化剂的可能性。本综述概述了将MOF和单原子结合以生成光催化剂的方法。同时也对这些基于MOF的单原子体系所面临的挑战进行了批判性审视。随着持续优化有助于更充分地利用其优势来提高光催化性能——以支持可持续发展的方式将阳光转化为化学品，本文还讨论了它们的未来发展。在此获得的见解可能会为实现基于MOF的单原子光催化剂的巨大潜力指明道路，从而推动由可再生太阳能驱动的生产。
