Emerging Synthesis Strategies of High-Entropy Intermetallic Nanocatalysts

High-entropy intermetallic (HEI) nanomaterials have recently been established as a representative class of high-performance nanocatalysts. However, the synthesis of HEI nanomaterials remains a significant challenge, with only a limited number of types being reported to date. This review aims to provide a systematical overview of the current state of research on HEI nanomaterials. The synthesis strategies are first discussed, with a special emphasis on the pivotal role that supports play in the formation of HEI nanomaterials. Following this, we provide a summary of key catalytic applications and focus on the structure-performance relationships. Finally, the review concludes by discussing the challenges faced in this area and suggesting potential research directions for the future.
