Metal nanoparticles play a crucial role in electrocatalysis, but achieving a uniform composition and structure at the atomic level and establishing correlations between catalytic properties and nanoparticle structure is challenging. Ligand-passivated metal nanoclusters, as model catalysts, show great potential in electrocatalysis research. This review summarizes the progress in utilizing atomically precise metal nanoclusters for electrocatalysis and highlights the factors affecting catalyst activity and selectivity.
Metal nanoparticles occupy an important position in electrocatalysis. Unfortunately, by using conventional synthetic methodology, it is a great challenge to realize the monodisperse composition/structure of metal nanoparticles at the atomic level, and to establish correlations between the catalytic properties and the structure of individual catalyst particles. For the study of well-defined nanocatalysts, great advances have been made for the successful synthesis of nanoparticles with atomic precision, notably ligand-passivated metal nanoclusters. Such well-defined metal nanoclusters have become a type of model catalyst and have shown great potential in catalysis research. In this review, the authors summarize the advances in the utilization of atomically precise metal nanoclusters for electrocatalysis. In particular, the factors (e.g., size, metal doping/alloying, ligand engineering, support materials as well as charge state of clusters) affecting selectivity and activity of catalysts are highlighted. The authors aim to provide insightful guidelines for the rational design of electrocatalysts with high performance and perspectives on potential challenges and opportunities in this emerging field.
