Article Synopsis
  • Electrochemical extraction of uranium from seawater offers a sustainable fuel source for nuclear energy, but traditional methods require high voltages (~-5 V).
  • Researchers developed S-terminated MoS nanosheets, which effectively bind and reduce uranium at a lower voltage (-3 V), achieving an extraction capacity of 1823 mg/g in uranium-spiked seawater.
  • By using a reverse potential, they concentrated real seawater samples, demonstrating the ability to extract significant amounts of uranium while also observing uranium clusters at atomic resolution, which enhances the extraction process.

The reduction of U(VI) to U(IV) in wastewater by semiconductor photocatalysis has become a new highly efficient and low-cost method for U(VI) removal. However, due to the weak absorption of visible light led by wide band gap and low carrier utilization rate resulted from the severe electron-holes recombination, the photoreduction performance of U(VI) is limited. Herein, the Ti vacancies and doped Fe atoms were simultaneously introduced into TiO nanosheet (labeled as 4%Fe-TiO) as a highly active and stable catalysis for U(VI) photoreduction.
