SnO2-isolated Pt3Sn alloy on reduced graphene oxide: an efficient catalyst for selective hydrogenation of C[double bond, length as m-dash]O in unsaturated aldehydes

Abstract

In this communication, a pyramid shaped alloy-metal oxide–graphene hybrid was synthesized by a facile procedure, in which SnO2 nanoparticles (NPs) (4.8–5.8 nm) were first coated onto the surface of reduced graphene oxide (rGO), and then very fine Pt3Sn NPs (0.6–1.2 nm) were fabricated on the SnO2 NPs on rGO sheets under microwave irradiation in a few minutes. Characterizations disclosed that the SnO2 NPs on rGO were more favorable for the dispersion of Pt, and Pt3Sn formed mainly on the surface of SnO2 NPs. This pyramid shaped Pt3Sn/SnO2/rGO hybrid was highly active, selective and stable for the hydrogenation of the C[double bond, length as m-dash]O bond in unsaturated aldehydes to unsaturated alcohols under mild conditions.
