Title
Preparation of SiO2-encapsulated SnPt nanoparticle catalysts for selective hydrogenation of unsaturated aldehyde
Abstract

The SiO2-encapsulated SnPt catalysts having the core–shell structures were prepared by using the polyol process. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) results indicated the SnPt alloy nanoparticles were covered with a thin silica layer with the porous structures. The SiO2-encapsulated SnPt catalysts showed the higher selectivity of crotyl alcohol for selective hydrogenation of crotonaldehyde in comparison with the Sn-Pt/SiO2 catalysts prepared by a conventional co-impregnation. It was considered that the formation of uniform SnPt alloy phases and the pore structures in the silica layers with the steric hindrance would enhance the chemo-selective hydrogenation of crotonaldehyde.
