Abstract: The evolution of metal-organic frameworks (MOFs)-based heterojunction photocatalysts signifies notable progress in solar energy conversion and environmental applications, offering enhanced performance through improved charge separation and light absorption. This review highlights recent progress in the synthesis, modification, and applications of MOF-based heterojunctions. We first examine the development of heterojunctions and their integration within MOF structures, which improves photocatalytic performance. Different kinds of heterojunctions, such as Z-scheme, S-scheme, Type II, p-n junctions, Schottky, quantum dots, and isotype heterojunctions, are examined, each with distinct charge transfer mechanisms. This review also summarizes key synthetic methodologies, including hydrothermal, solvothermal, electrostatic self-assembly, and in-situ calcination methods, illustrating how these methods improve heterojunction formation for enhanced the photocatalytic properties. Additionally, different MOF compositions spanning metal and non-metal based, as well as carbon, sulfides, carbides, COFs, CMPs, and CTFs-based MOFs are outlined, emphasizing their significance in photocatalytic applications. Finally, we discuss the diverse photocatalytic applications of these heterojunctions, encompassing photocatalytic applications such as hydrogen evolution reaction (HER), oxygen evolution reaction (OER), overall water splitting, CO 2 reduction, nitrogen fixation, H 2 O 2 production, and degradation. This review highlights the significant potential of MOFs-based heterojunctions in tackling energy and environmental issues, while offering insights into future strategies for enhancing their performance in photocatalysis.
