Spillover is a well-known phenomenon in heterogeneous catalysis and is involved in many important reactions. The establishment of the spillover concept opened up a new research field for an in-depth understanding of the dynamic behavior of migrated species on a catalyst surface. However, a comprehensive understanding of spillover remains lacking. In recent years, the development of advanced characterization techniques in combination with well-controlled synthesis methodologies has provided us with increasing worthwhile information about spillover. This Review mainly describes recent progress on the characterization and mechanism of hydrogen spillover and how to effectively utilize the spillover effect for enhanced catalytic performance. Additionally, the challenges remaining in this research area are discussed, and possible research directions for the future are proposed.

异构催化中的溢出：新的见解和机遇

溢出是非均相催化中众所周知的现象，并且涉及许多重要的反应。外溢概念的建立为深入了解催化剂表面上迁移物种的动态行为开辟了一个新的研究领域。但是，仍然缺乏对溢出的全面了解。近年来，先进的表征技术与良好控制的合成方法相结合的发展为我们提供了有关溢出的越来越有价值的信息。这篇综述主要描述了氢溢出的表征和机理的最新进展，以及如何有效利用溢出效应来增强催化性能。此外，还讨论了该研究领域中仍然存在的挑战，
