ABCABC Stacking-Enabled Non-Centrosymmetry 3R-ZnIn₂S₄ Nanosheets for Piezocatalytic Uranium Extraction. [PDF]

Adv Sci (Weinh)
The ABCABC stacking sequence in 2D ZnIn2S4 nanosheets creates intrinsic non‐centrosymmetry, enabling robust piezocatalysis under weak mechanical agitation. The nanosheets achieve a H2O2 yield of 276.7 µmol g−1 h−1 and uranium extraction capacity of 763.2 mg g−1 via a dual mechanism of direct piezoreduction and in situ H2O2 complexation.

In Situ Metal-Oxygen-Hydrogen Modified B-Tio₂ @Co₂ P-X S-Scheme Heterojunction Effectively Enhanced Charge Separation for Photo-assisted Uranium Reduction. [PDF]

Adv Sci (Weinh)
Photo‐assisted uranium reduction from uranium mine wastewater is expected to overcome the competition between impurity ions and U(VI) in the traditional process.

Unlocking Zenith Electronic State of Ni Sites in Ligand-Engineered COFs for Efficient •O₂ ^--Driven Uranium Photoreduction. [PDF]

Adv Sci (Weinh)
We develop a ligand engineering strategy to construct Ni‐diketimine‐linked COFs with precisely tuned Ni electronic states. By varying the coordinated diketone units, we achieve an optimal electronic configuration that enhances O2 adsorption and lowers the energy barrier for •O2− generation.
