摘要

本文以Fe- zif -8为前驱体，通过煅烧将铁单原子锚定在缺氮的g-C3N4 （ND-CN）上，合成了一种新型的Fe/ND-CN复合材料。该材料作为光催化工作电极，在光和外加电压下还原U（VI）。值得注意的是，在pH 5.0下，它几乎完全去除了U(VI)（99.2%）。所阐明的机理为低浓度铀废水的高效处理提供了技术和理论基础。

Efficient photoelectrocatalytic reductive elimination of uranium(VI) using iron single-atom-doped defect-engineered C3N4

In this work, a novel Fe/ND-CN composite was synthesized by anchoring iron single atoms onto nitrogen-deficient g-C₃N₄ (ND-CN) using Fe-ZIF-8 as a precursor via calcination. This material served as a photoelectrocatalytic working electrode for U(VI) reduction under light and applied voltage. Remarkably, it achieved near-complete U(VI) removal (99.2%) at pH 5.0. The elucidated mechanism provides a highly efficient technique and theoretical foundation for low-concentration uranium wastewater treatment.
