“…Wang's group designed a composite material made of a magnetic core and a zeolite imidazolate framework (ZIF-8) shell surrounded by carbon dots (CDs) to simultaneous sensing and removal of uranium ion in water. 110 Fe 3 O 4 -CMC@ZIF-8@CDs had a large adsorption capacity of 606.06 mg g −1 . Moreover, the fluorescence intensity decreased close to detection limit as the U( vi ) concentration increased to 100 mg L −1 .…”

The steady supply of uranium resources and the reduction or elimination of the ecological and human health hazards of wastewater containing uranium make the recovery and detection of uranium in water greatly important. Thus, the development of effective adsorbents and sensors has received growing attention. Metal–organic frameworks (MOFs) possessing fascinating characteristics such as high surface area, high porosity, adjustable pore size, and luminescence have been widely used for either uranium adsorption or sensing. Now pertinent research has transited slowly into simultaneous uranium adsorption and detection. In this review, the progress on the research of MOF-based materials used for both adsorption and detection of uranium in water is first summarized. The adsorption mechanisms between uranium species in aqueous solution and MOF-based materials are elaborated by macroscopic batch experiments combined with microscopic spectral technology. Moreover, the application of MOF-based materials as uranium sensors is focused on their typical structures, sensing mechanisms, and the representative examples. Furthermore, the bifunctional MOF-based materials used for simultaneous detection and adsorption of U(VI) from aqueous solution are introduced. Finally, we also discuss the challenges and perspectives of MOF-based materials for uranium adsorption and detection to provide a useful inspiration and significant reference for further developing better adsorbents and sensors for uranium containment and detection.

“…These Fe3O4-CMC@Z1F-8@CD composites displayed better adsorption (173.60 mg/g) compared to the Fe3O4-CMC@Z1F (96.02 mg/g). The greater adsorption was attributed to the large surface area and abundant N/O containing functional groups present on the surface of the carbon dots [35].…”

Among the various types of metal organic frameworks (MOFs), the metal-oxide-based ones fulfill all the essential criteria such as strong bonding, organic linking units, and highly crystalline nature, properties required to be effective photocatalysts to serve environmental remediation. Moreover, the even spread of active sites and semiconductor properties make the MOFs ideal for absorbing irradiation from UV as well as visible light sources. Metal oxide composites with carbon based materials, especially, show high photocatalytic activity toward the degradation of organic dyes. Considering the relatively low cost of metal oxide semiconductors compared to pure metallic nanoparticles, metal oxide composites can provide a great alternative as photocatalysts especially considering the adjustable bandgaps and synergistic effects. Therefore, the metal oxide application as the photocatalysts in industry and technology in terms of techno-economic advantage is attracted. In this study, energy sustainability and solving carbon-related issues through metal oxide-based materials are discussed. This study aims to review metal oxide composites including metal oxide-MOFs and metal oxide-carbon material compositions as photocatalysts, application, merits in environmental and energy systems performances, and its contribution as an influential factor for sustainable development.
