High-entropy spinel (HES) compounds, as a typical class of high-entropy materials (HEMs), represent a novel frontier in the search for next-generation catalysts. Their unique blend of high entropy, compositional diversity, and structural complexity offers unprecedented opportunities to tailor catalyst properties for enhanced performance (, activity, selectivity, and stability) in heterogeneous reactions. However, there is a gap in a critical review of the catalytic applications of HESs, especially focusing on an in-depth discussion of the structure-property-performance relationships. Therefore, this review aims to provide a comprehensive overview of the development of HESs in catalysis, including definition, structural features, synthesis, characterization, and catalytic regimes. The relationships between the unique structure, favorable properties, and improved performance of HES-driven catalysis are highlighted. Finally, an outlook is presented which provides guidance for unveiling the complexities of HESs and advancing the field toward the rational design of efficient energy and environmental materials.
高熵尖晶石（HES）化合物作为一类典型的高熵材料（HEM），是寻找下一代催化剂的新前沿领域。它们独特地融合了高熵、成分多样性和结构复杂性，为定制催化剂性能以增强多相反应中的性能（活性、选择性和稳定性）提供了前所未有的机会。然而，对高熵尖晶石催化应用的批判性综述存在空白，尤其缺乏对结构-性能-反应关系的深入讨论。因此，本综述旨在全面概述高熵尖晶石在催化领域的发展，包括定义、结构特征、合成、表征及催化机制。重点阐述了高熵尖晶石驱动催化的独特结构、优良性能和提升性能之间的关系。最后，给出了展望，为揭示高熵尖晶石的复杂性以及推动该领域向高效能源与环境材料的合理设计发展提供指导。
