Wet Chemical Synthesis of Cu-Based Alloys and Their Electrocatalytic Applications

Cu-based alloys, which are known for their abundant electroactive sites and excellent stability, have emerged as promising electrocatalytic materials for sustainable energy conversion. Among the various synthetic strategies, wet chemical methods offer a mild, efficient, and controllable approach to precisely tailor the composition and structure of Cu-based alloys, thereby optimizing their electrocatalytic properties. This review highlights recent advances in wet chemical synthesis techniques, including hydrothermal, solvothermal, polyol, and seed-mediated methods. Furthermore, it explores the applications of Cu-based alloys in key electrocatalytic reactions, such as alcohol oxidation, carbon dioxide reduction, nitrogen-related transformations, hydrogen evolution, and oxygen reduction. Finally, the challenges and prospects of Cu-based alloy electrocatalysts are discussed, providing insights into the design and development of high-performance energy-conversion technologies.
