A Supramolecular Organic Framework‐Mediated Electrochemical Strategy Achieves Highly Selective and Continuous Uranium Extraction

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: June 26, 2024

Abstract The integration of selectivity and electron transfer ability remains a primary challenge in developing electrode materials for uranium electroextraction. Herein, phenanthroline‐based supramolecular organic framework (MPSOF) is elaborately constructed as pioneering cathode material through the hydrogen bond‐driven self‐assembly melamine 1,10‐phenanthroline 2,9‐dicarboxylic acid (PDA) selective continuous electrochemical extraction (EUE). PDA moieties selectively capture UO 2 2+ , while bond‐supporting frameworks provide an efficient channel redox . These structural features enable rapid formation spontaneous shedding precipitate from MPSOF, allowing regeneration adsorption sites. As result, MPSOF‐mediated EUE exhibits high capacity 7311 mg U g −1 at low voltage −3.5 V but does not reach equilibrium. Cyclic employed to simulated high‐salt radioactive effluents attains uranium. electroextraction mechanism confirmed, wherein species transform into (UO )O ·4H O. This work only provides electroextraction, also presents novel strategy separation other radionuclides contaminant ions.

Morphology Effect of FeWO₄ Boosting Efficiency of Photocatalytic Uranium Extraction under Visible Light and Mechanism Investigation

Langmuir, Journal Year: 2025, Volume and Issue: unknown

Published: March 14, 2025

Wolframite (FeWO4) is a type of polyoxometalate known for its high chemical stability and electronic properties, which makes it an excellent photocatalyst. While FeWO4 has been widely utilized in the domain organic catalysis, there are currently no documented reports regarding use degradation U(VI). In this study, effect changing microscopic morphology catalyst to enhance photocatalytic activity was explored. We effectively adjusted microstructure crystallinity by varying hydrothermal synthesis temperature, subsequently analyzed detail using synchrotron radiation theoretical calculations. Additionally, rate U(VI) nuclear wastewater reached 98.8% samples synthesized at 200 °C, coexisting ions on performance studied, results showed that certain amounts Na+, Mg2+, K+, Ca2+ almost negligible, still maintained more than 90% initial after six cycles, highlights wide application prospects field treatment future. Therefore, exhibits uranium-extraction ability, anti-interference stability, low-cost advantage. It holds great extracting radioactive uranium from wastewater.
