The strong metal-support interaction (SMSI) is one of the most important concepts in heterogeneous catalysis, which plays a crucial role modifying catalytic performance. However, study SMSI on single-atom catalysts (SACs), are considered to bridge homogeneous and remains preliminary. Here, best our knowledge, we first report oxidative SMSIs SACs utilize them enhance hydroformylation activity stability. surface-adsorbed Rh single atoms tend be encapsulated by ZrO2 supports after calcination air can re-exposed reduction H2. highest turnover frequency (TOF) reaches 11,097 h-1, surpassing previously reported SACs. embedded Rh, generated through SMSI, also shows enhanced stability resist metal leaching. Our work expands conceptual boundaries paves way for future design highly active stable catalysts.

Catalytic transfer hydrogenation (CTH) using Cu nanocatalysts offers significant advantages over direct high-pressure hydrogenation. However, the active hydrogen (H*) in this process exhibits poor adsorption and tends to release H
