Research Progress on Supports for Rh-Based Catalysts in Heterogeneous Hydroformylation of Olefins

• • Rh1/CeO2 catalysts exhibit morphology-dependent activity, with specific facets enhancing hydroformylation performance, as demonstrated by molecular-level studies (ACS Catal. 2024, 14, 15956). • • Rh/activated carbon catalysts modified with surface oxygen-containing groups achieve improved catalytic performance in 1-hexene hydroformylation, with enhanced activity and selectivity (Appl. Catal. A 2016, 527, 53). • • Porous monophosphine polymers confine atomically dispersed Rh, enabling regioselective hydroformylation of alkenes with high linear aldehyde selectivity (J. Catal. 2021, 401, 321). • • Dual-active-site catalysts comprising Rh-N4 single atoms and Rh clusters on supports achieve ultra-high turnover frequency (TOF) in heterogeneous hydroformylation, demonstrating synergistic effects (Chem. Eng. J. 2024, 479, 147505).
