Pd nanoparticles confined in fluoro-functionalized yolk-shell-structured silica for olefin hydrogenation in water

doi:10.1016/S1872-2067(12)60561-0

Abstract

Abstract:

Pd nanoparticles were confined in yolk-shell mesoporous silica via encapsulation, etching and modification, producing a functionalized yolk-shell-structured catalyst. This catalyst was characterized using X-ray diffraction analysis, transmission electron microscopy, N₂ adsorption-desorption, and thermogravimetric analysis. The catalyst had high activity for olefin hydrogenation in water, higher than that of the unmodified counterpart. The catalyst can be recovered through centrifugation, and its activity is not significantly decreased after several reaction cycles.

Key words: Palladium, Functionalization, Olefin, Aqueous phase, Hydrogenation
