Abstract Controlling the metal geometric and electronic structure is of significance in developing efficient catalysts for heterogeneous hydroformylation. This study examines structural sizes Rh + ‐Rh 0 distribution to construct a highly active catalyst formaldehyde The sites hydroformylation require several n atoms, while single‐atom can solely catalyze hydrogenation. highest activity was achieved on nanoclusters (0.95 nm), giving TOF 191 h −1 selectivity 82% glycolaldehyde formation. tunability properties synergistic interaction between are essential enhanced activity. Pseudo‐ situ FT‐IR analysis elucidated that adsorbed nanocluster prefers produce via hydroformylation, isolated δ+ tends form methanol provides new insight into design guidance understanding reaction mechanism aldehydes/olefins
