Abstract

Electrochemical Water Splitting Systems

In article number 2400059, Young Soo Kang, Uk Sim, and co-workers study and present the synthesis of Ni/Ni₃N@NC and their application as dual-functional catalysts in water electrolyzers. The accelerated electrochemical oxygen and hydrogen evolution reaction (EOER/EHER) is due to its heterostructure and ambipolar behavior leading to the presence of active sites for EOER and EHER, as confirmed by in-situ Raman analysis.

在电化学水分离系统中，Ni/Ni3N@NC 的双极性加速了氢氧同时进化的双重功能（Adv.）

电化学水分离系统在文章编号 2400059 中，Young Soo Kang、Uk Sim 及其合作者研究并介绍了 Ni/Ni3N@NC 的合成及其作为双功能催化剂在水电解槽中的应用。经原位拉曼分析证实，加速电化学氧气和氢气进化反应（EOER/EHER）的原因是其异质结构和伏极行为导致了 EOER 和 EHER 活性位点的存在。
