Abstract

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. More details can be found in article number 2400260 by Sandip De, Schirin Hanf, and co-workers.
