NiCo bimetallic nanoparticles encapsulated in graphite-like carbon layers as efficient and robust hydrogenation catalysts

Abstract

Catalytic hydrogenation by transition metal catalysts instead of noble metal catalysts has attracted considerable attention. Herein, the alloyed NiCo bimetallic nanoparticles encapsulated in nitrogen doped graphite-like carbon layers (NixCo1-x@NC) with the controllable chemical compositions delivered the high catalytic performance for hydrogenation of alkenes, alkynes and nitroarenes. The NixCo1-x@NC catalysts exhibited a strong chemical composition-depended catalytic hydrogenation activity, in which the Ni0.5Co0.5@NC catalysts delivered the best performance. X-ray photoelectron spectroscopic analysis demonstrate that the highest catalytic performance of the Ni0.5Co0.5@NC catalysts is attributed to their optimized electronic structure for the efficient hydrogen activation.
