氟诱导的Cu3P双缺陷电子重分布加速电荷转移，实现高效电化学去除氯离子。

电化学氯离子去除对清洁水和环境保护至关重要，但其实际应用受到动力学缓慢的阻碍，特别是在高质量负载电极上。传统的外部修饰，如导电添加剂或结构设计，表现出有限的有效性。在这里，我们报告了一种通过杂原子掺杂诱导双缺陷工程的内在增强策略，并通过熔盐处理成功合成了含磷空位的氟掺杂磷化铜（F-Cu3PV）。基于密度泛函理论计算和实验结果，F掺杂引起晶格畸变，产生P空位形成双缺陷。这些缺陷有效地调节了本征电子再分布，从而改善了导电性能，增强了吸附能力，降低了氯离子扩散能垒。因此，电子转移和离子扩散动力学显著加快，从而导致优异的电化学性能。结果表明，F-Cu3PV电极具有优异的电化学氯离子去除性能，具有优异的面积去离子容量（3.16±0.02 mg cm-2）和非常快的面积去离子速率（0.106±0.001 mg cm-2 min-1），以及出色的循环稳定性（70次循环后保留率为95.65%）。这项工作阐明了通过杂原子掺杂诱导的双缺陷进行电子重分配是克服高性能电化学氯离子去除固有动力学瓶颈的可行途径。

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
