Abstract

Abstract: The synthesis of novel nanoparticles is of general importance for the development of efficient heterogeneous catalysts. Herein, the preparation of carbon‐supported nickel‐based nanoparticles (NPs), modified by nitrogen‐doped graphene layers, is reported for the first time. The resulting materials were characterized in detail by TEM, X‐ray photoelectron spectroscopy (XPS), XRD, elemental analysis (EA), electron paramagnetic resonance (EPR), temperature‐programmed reduction (TPR), BET, and Raman analysis. Initial catalytic tests revealed the potential of this class of compounds in hydrogenation reactions. Abstract : Novel nanoparticles : A novel heterogeneous nickel catalyst is synthesized by impregnation of Vulcan ® XC72R by a nickel/1, 10‐phenanthroline complex and subsequent pyrolysis. The structure of the heterogeneous material is elucidated and the catalyst possesses interesting activity in different hydrogenation reactions.
