Abstract
En 中文
Structurally ordered high-entropy intermetallics (HEIs) have garnered increased attention due to their unique physicochemical properties. The ordered atomic configuration and compositional diversity of HEIs contribute to optimal active-site isolation, broad tunability of catalytic activity, and remarkable electrochemical stability. These advantages have enabled HEIs to achieve exceptional catalytic performance in various energy-related applications, positioning them as promising candidates for next-generation catalytic materials. However, comprehensive reviews on HEIs are scarce. This work provides a systematic overview of recent advances in HEIs research, encompassing innovative synthesis strategies, advanced characterization techniques, and catalytic applications such as the oxygen reduction reaction, hydrogen evolution reaction, electrochemical nitrate reduction reaction, and small-molecule oxidation reactions. Furthermore, the unique catalytic properties of HEIs are thoroughly elucidated, while discussing the challenges and future research opportunities for HEI-based catalysts. This work highlights the transformative potential of HEIs in driving the development of energy-related catalytic technologies and provides valuable insights for designing next-generation high-performance catalysts.
