通过缺陷工程和碳支撑实现掺镍 CoP3 在整体水分离中的高催化活性。

本研究报告介绍了如何利用缺陷工程和碳支撑技术实现具有高活性和高稳定性的金属掺杂磷化物，用于碱性介质中的氢进化反应（HER）和氧进化反应（OER）。具体而言，通过等离子体辅助磷化法合成了碳布上具有丰富 P 缺陷（Pv-）的氮掺杂碳纳米纤维支撑的镍掺杂 CoP3（p-NiCoP/NCFs@CC）。p-NiCoP/NCFs@CC 是一种高效稳定的 HER 和 OER 催化剂。它只需要 107 和 306 mV 的过电位就能分别驱动 100 mA cm-2 的 HER 和 OER。其催化活性高于最近报道的其他催化剂。p-NiCoP/NCFs@CC 的高活性主要源于其特殊的结构特征。密度泛函理论计算表明，Pv-富集、Ni掺杂和碳支撑可以优化催化剂表面对 H 原子的吸附，促进碳纳米纤维支撑的 p-NiCoP 与 OER 过程中形成的表面氧化层之间的强电子耦合。因此，p-NiCoP/NCFs@CC 具有很高的 HER 和 OER 活性。在碱性水电解槽中使用时，p-NiCoP/NCFs@CC 在整体水分离方面表现出卓越的活性和稳定性。

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.
