Palladium nanoparticles as hydrogenation catalysts — •Petra de Jongh, Jessi van der Hoeven, and Oscar Brandt Corstius — Debye Institute for Nanomaterials Science, Utrecht University, Utrecht The Netherlands

Regarding metal hydrogen interaction, palladium is one of the most investigated systems. An interesting application of this interaction is the use of palladium as hydrogenation catalyst. Due to its electronic properties and hence strong interaction with the dihydrogen molecule, palladium is one of the fastest hydrogenation catalysts (about six orders of magnitude faster than for instance copper), but a challenge is to control the surface properties of palladium to such an extent that it is also selective.

In this contribution I will introduce supported Pd nanoparticles as hydrogenation catalysts, and share some recent results of our group on the effect of Pd nanoparticles size, and the influence of alloying these nanoparticles with a second metal such as copper or gold.

Keywords: palladium; nanoparticles; catalysis; hydrogenation
