摘要
高熵合金纳米粒子(HEA-NPs)最近在材料科学领域引发了极大的兴趣。它们的固溶状态源自不同的 HEA 构型,使其成为具有优异活性、稳定性和可调性能的催化剂的理想候选材料。然而,人们对其电催化行为的基本机制仍缺乏全面的了解,这阻碍了 HEA 电催化剂的合理设计。本综述总结了 HEA-NPs 的基础知识,包括 HEA-NPs 的结构-活性相关性、多种合成策略以及在电化学催化中的应用。重点介绍了指导改善可调性能的设计策略。文章最后提出了见解、观点和未来方向,概括了最先进的知识,为这一充满活力的领域的进一步探索铺平了道路。
Structural insights, synthesis, and electrocatalysis of high entropy nanoparticles for fuel cell, metal-air battery, and water-splitting applications
High-entropy alloy nanoparticles (HEA-NPs) have recently sparked great interest in materials science. Their solid-solution states, derived from distinct HEA configurations, make them promising candidates for catalysts with exceptional activity, stability, and tunable performance. However, a comprehensive understanding of the underlying mechanisms governing their electrocatalytic behavior is still lacking, hindering the rational design of HEA electrocatalysts. This review summarizes the fundamental knowledge of HEA-NPs, including the structure-activity correlations of HEA-NPs, diverse synthesis strategies, and applications in electrochemical catalysis. The design strategies for guiding improvements in tunable performance were highlighted. The article concludes with insights, perspectives, and future directions, encapsulating the state-of-the-art knowledge and paving the way for further exploration in this dynamic field.
