Abstract

Recent advances in single-atom alloy (SAA) catalysts provide a unique platform for understanding spillover, due to the well-defined nature of the active site for dissociative chemisorption. In particular, the use of spilled adsorbates following molecular dissociation on the host metal surface facilitates the generation of high-value chemicals in subsequent catalytic reactions. Nevertheless, the factors that control the spillover process remain to be fully elucidated. This perspective discusses recent theoretical advances in the spillover dynamics on SAAs, with a particular focus on the dissociation and spillover processes of H2 and CH4. It provides valuable insights into how various factors, such as energy transfer, nuclear quantum effects, gas-adsorbate interactions, and adsorbate size, impact the diffusion behavior of hydrogen and methyl species on SAA surfaces. The article concludes with a discussion of future prospects. This perspective underscores the significance of spillover dynamics in heterogeneous catalysis, with important implications for improving catalytic performance.

期刊介绍: Computational molecular sciences harness the power of rigorous chemical and physical theories, employing computer-based modeling, specialized hardware, software development, algorithm design, and database management to explore and illuminate every facet of molecular sciences. These interdisciplinary approaches form a bridge between chemistry, biology, and materials sciences, establishing connections with adjacent application-driven fields in both chemistry and biology. WIREs Computational Molecular Science stands as a platform to comprehensively review and spotlight research from these dynamic and interconnected fields.
