Shape Control Preparation of Supported Platinum Nano-octahedra by Ethylene Treatment for Enhancement of Selective Hydrogenation of Cinnamaldehyde
The particle shape of a Pt/C catalyst is confined to octahedral by adding ethylene in an H-2 stream during reduction of Pt/C. The Pt nano-octahedra enclosed by Pt{111} show higher catalytic activity for selective C=O hydrogenation of cinnamaldehyde in comparison with Pt nano-cuboctahedron, cube, and sphere.
