Rh₂P Nanoparticles Stabilized by Carbon Patches for Hydroformylation of Olefins

Rh2P nanoparticles (NPs) have been identified as suitable mimics of [RhI(Ph3P)3]+, the benchmark homogeneous catalysts in liquid-phase hydroformylation. For this reason, a fitted synthetic strategy is required to develop based exclusively on NPs. To attain this, two pathways devised. In first one, separate sources Rh and P were used. second Wilkinson complex was employed unique source probe positive influence well-defined molecular organization preparation dispersed controlled nanoparticles, stabilized by carbon patches formed during pyrolysis treatment from PPh3. addition, metallic also synthesized be used reference. All compared means of: transmission electron microscopy, X-ray diffraction, adsorption spectroscopy. The application XAS study NPs unusual has essential discussion results. Starting with metal precursor leads exclusive formation excellent catalytic activity for role modulate particle size electronic configuration species, resulting improvement performance obtention turnover frequencies 5236 h–1 at 60 °C 17,788 100 °C.
