Framework tin ions in the Sn-beta sample stabilize the nucleation of platinum nanoparticles inside the zeolite channel. These Pt-0-Sn4+ sites, which are only observed in the Pt/Sn-beta catalyst, have been shown to strongly activate the carbonyl group enhancing the hydrogenation rate of the C=O bond.Reserva de todos los derechosQUIMICA ORGANICAArtículo10.1039/c3cp50519gCerrado
