While cathodic corrosion may appear as an undesired degradation process at electrode surfaces, it has become a powerful electrochemical method for fabricating nanoparticles and single-atom catalysts. In contrast to traditional wet chemical synthesis, cathodic corrosion affords rapid, straightforward, capping-agent-free production of nanoparticles, enabling fine control over size, shape, and elemental composition. This mini-review summarizes recent advances in cathodic corrosion-based synthesis, emphasizing its unique capabilities for producing metallic, alloyed, and oxide nanoparticles, as well as single-atom catalysts. It explores the effects of varying parameters such as electrode material, electrolyte composition, voltage waveform, and frequency on the characteristics of the generated particles. Furthermore, it highlights the enhanced electrocatalytic or photoelectrocatalytic performance of the nanoparticles produced via cathodic corrosion.
虽然阴极腐蚀在电极表面可能表现为一种不期望的降解过程，但它已成为制备纳米颗粒和单原子催化剂的一种强大的电化学方法。与传统的湿化学合成相比，阴极腐蚀能够快速、直接地生产无封端剂的纳米颗粒，从而能够对尺寸、形状和元素组成进行精细控制。本综述总结了基于阴极腐蚀的合成方法的最新进展，重点介绍了其在制备金属、合金和氧化物纳米颗粒以及单原子催化剂方面的独特能力。它探讨了诸如电极材料、电解质组成、电压波形和频率等不同参数对所生成颗粒特性的影响。此外，它还强调了通过阴极腐蚀制备的纳米颗粒增强的电催化或光电催化性能。
