Abstract

Metal-organic frameworks (MOFs) have emerged as ideal carriers in photocatalysis owing to their high specific surface area, precisely tunable pore channels, and adjustable electronic structures. However, most MOFs suffer from weak visible-light response and facile recombination of photogenerated charge carriers. The dye-sensitization strategy, which constructs dye-MOF heterojunctions, can effectively broaden the light absorption range of materials and enhance interfacial charge separation and transport, representing an important pathway to overcome the limitations of traditional MOF and inorganic semiconductor-sensitized systems. This review summarizes the characteristics of dye-sensitized MOFs; elaborates on the mechanisms of electron injection, energy transfer, interfacial interactions, and multi-component synergistic catalysis in heterojunction construction; and surveys the research progress of these materials in photocatalysis
