Abstract Photocatalysis is considered to be a green and environment‐friendly technology since it can convert solar energy into other types of chemical energies. Over the past several years, metal‐organic frameworks (MOFs)‐based photocatalysts have received remarkable research interest due their unique morphology, high photocatalytic performance, good stability, easy synthesis, low cost. In this review, synthetic strategies developing MOFs‐based are first introduced. Second, recent progress in fabrication various MOFs composites summarized. Third, different applications including hydrogen evolution reaction, oxygen overall water splitting, nitrogen reduction carbon dioxide reaction as well photodegradation organic pollutants summed up. Finally, challenges some suggestions for future development MOFs‐ composites‐based also highlighted. It expected that report will help researchers systematically devise develop highly efficient based on composites.

Metal–organic frameworks (MOFs) have been frequently used as photocatalysts for the hydrogen evolution reaction (HER) using sacrificial agents with UV–vis or visible light irradiation. The aim of present review is to summarize use MOFs solar-driven targeting overcome current efficiency limitations in overall water splitting (OWS). Initially, fundamentals photocatalytic OWS under solar irradiation are presented. Then, different strategies that can be implemented on adapt them photocatalysis discussed detail. Later, most active reported until now HER and/or oxygen (OER) critically commented. These studies taken precedents discussion existing sunlight requirements met at large scale also discussed. last section this provides a summary state field and comments future prospects could bring closer commercial application.

Abstract Reduction of soluble hexavalent uranium (U(VI)) to sparingly tetravalent (U(IV)) with semiconductor photocatalysts is recognized as a novel, green, and simple U‐extraction method. Furthermore, effective charge separation utilization are critical factors achieve high‐efficiency U(VI) photoreduction. Herein, UiO‐66‐based heterostructured photocatalyst (MnO x /UiO‐66/Ti 3 C 2 T ) spatially separated dual cocatalysts nanoparticles Ti MXene nanosheets) successfully developed for efficient photoreduction without sacrificial agents. As co‐catalysts, MnO favor the trapping holes, while nanosheets tend collect electrons. Consequently, photogenerated holes electrons flow into out photocatalyst, respectively, achieving required by remove U(VI). Impressively, removal ratio via reaches 98.4% in solution after 60 min, photoreaction rate constant 0.0948 min −1 . Moreover, exhibits brilliant extraction capacity various wastewater U(VI)‐spiked real seawater.

Solar energy is a key sustainable resource, and materials with optimal properties are essential for efficient solar energy-driven applications in photocatalysis. Metal-organic frameworks (MOFs) excellent platforms to generate different nanocomposites comprising metals, oxides, chalcogenides, phosphides, or carbides embedded porous carbon matrix. These MOF derived offer symbiosis of like high crystallinities, inherited morphologies, controllable dimensions, tunable textural properties. Particularly, adjustable band positions achieved by situ tailored self/external doping surface functionalities make these promising photocatalysts. Despite some progress this field, fundamental questions remain be addressed further understand the relationship between structures, properties, photocatalytic performance nanocomposites. In review, synthesis approaches including self-template external-template methods produce various dimensions (0D, 1D, 2D, 3D), chemical compositions, bandgaps, comprehensively summarized analyzed.

The presence of persistent organic pollutants (POPs) in the aquatic environment is causing widespread concern due to their bioaccumulation, toxicity, and possible environmental risk. These contaminants are produced daily large quantities released into water bodies. Traditional wastewater treatment plants ineffective at degrading these pollutants. As a result, development long-term effective POP removal techniques critical. In water, adsorption photocatalytic degradation POPs have been identified as energy cost-efficient solutions. Both technologies received lot attention for efforts treat world's wastewater. Photocatalytic promising, effective, long-lasting method, while represents simple, practical particularly decentralized systems isolated areas.
