Studying the modulation of nanoclusters at an atomic scale is crucial for understanding the correlation between properties and catalytic performance. In this study, we synthesized and characterized Pd-n (n = 2-5) nanoclusters coordinated with di-1-adamantylphosphine. Pd-5 nanoclusters exhibited the highest catalytic performance (conversion = 99.3%, selectivity = 95.3%) for the hydrogenation of cinnamaldehyde to hydrocinnamaldehyde, with XPS identifying Pd & delta;+ as the key active component. The objective of this work was to explore the relationship among the number of Pd atoms, their electronic structure, and catalytic activity.
