Nitrogen-Rich Porous Carbon-Stabilized Ni-Co Nanoparticles for the Hydrogenation of Quinolines

Abstract

Synergistic effects of multimetallic catalysts play a crucial role in the field of heterogeneous catalysis, especially in the oxidation and reduction of functional groups. Hence, how to design a multimetallic catalyst with high catalysis performance attracts the attention of scientists. Herein, we have designed and synthesized a cobalt-nickel bimetallic catalyst step by step. More interestingly, the cobalt-nickel nanoparticles were encapsulated in N-doped hollow porous carbon (HPC), on which were grown many carbon tubes. The optimized nanoparticle as a hydrogenation catalyst exhibits superior performance in the selective reduction of quinoline at ambient temperature, due to its advantage of dispersing uniform bimetal nanoparticles and N-doped active sites.
