From Poison to Promotor: Spatially Isolated Metal Sites in Supported Rhodium Sulfides as Hydroformylation Catalysts
Hydroformylation Catalysts Supported RhxSy systems, particularly Rh17S15/SiO2, outperform metallic Rh catalysts in liquid-phase hydroformylation reactions. Machine learning, density functional theory, and structural analysis show that the incorporation of sulfur enhances the surface catalytic properties by improving substrate affinity. Consequently, Rh-rich terminations in Rh17S15 create highly reactive, spatially isolated Rh sites with tailored geometric and electronic properties, driving the superior catalytic performance.
