摘要

在这项研究中，铜硒纳米结构（Cu2Se Ns）通过简单的水热方法成功生长并集成到纳米针状结构氧化铜（Cu）网上。在空气气氛中，在400℃下对Cu网进行退火，形成纳米针。Cu₂Se电催化剂表现出优异的析氧反应（OER）活性，具有低过电位、增强的电荷转移动力学和长期的运行稳定性。

Selenium nanostructures grown on copper oxide nanoneedle for oxygen evolution reaction

In this study, copper selenium nanostructures (Cu₂Se Ns) were successfully grown and integrated onto a nanoneedle like structured oxidized copper (Cu) mesh via a simple hydrothermal approach. The nanoneedles were formed on the Cu mesh annealing at 400 °C in an air atmosphere. The Cu₂Se electrocatalyst exhibited excellent oxygen evolution reaction (OER) activity, with a low overpotential, enhanced charge transfer kinetics, and long-term operational stability.
