Cobalt (Co) is a promising candidate to replace noble metals in the hydrogenation process, which is widely employed in the chemical industry. Although the catalytic performance for this reaction has been considered to be significantly dependent on the Co crystal phase, no satisfactory systematic studies have been conducted, because it is difficult to synthesize metal nanoparticles that have different crystalline structures with similar sizes. Here we report a new method for the synthesis of cobalt nanoparticles using hydrosilane as a reducing agent (hydrosilane-assisted method). This new method uses 1,3-butanediol and propylene glycol to successfully prepare fcc and hcp cobalt nanoparticles, respectively. These two types of Co nanoparticles have similar sizes and surface areas. The hcp Co nanoparticles exhibit higher catalytic performance than fcc nanoparticles for the hydrogenation of benzonitrile under mild conditions. The present hcp Co catalyst is also effective for highly selective benzyl amine production from benzonitrile without ammonia addition, whereas many catalytic systems require ammonia addition for selective benzyl amine production. Mechanistic studies revealed that the fast formation of the primary amine and the prevention of condensation and secondary amine hydrogenation promote selective benzonitrile hydrogenation for benzylamine over hcp Co nanoparticles.

The surface structure of bimetallic catalysts is critical in determining their performance in hydrogenation reactions. In this study, we have developed a deep eutectic solvent-assisted solvothermal method to synthesize a highly efficient Pd 0.1 Co/CNTs-DES-40 nanocatalyst with a Co@Pd−Co core−shell structure. This Pd 0.1 Co/CNTs-DES-40 nanocatalyst demonstrated superior catalytic performance in the selective hydrogenation of furfural (FAL) to furfuryl alcohol (FOL) compared to other Pd−Co/CNT nanocatalysts with different structures (Janus type and alloy type), which were synthesized using successive impregnation and coimpregnation methods. The highest >99% FOL yield was achieved over the Pd 0.1 Co/CNTs-DES-40 catalyst. The arrangement of Pd and Co species in these systems was fully characterized, and detailed characterization revealed that the Co@Pd−Co core−shell nanostructure significantly increased the exposure of active sites and enhanced hydrogen adsorption and activation. Stability tests indicated a slight decrease in activity after six cycles, primarily due to the deposition of carbonaceous species and nanoparticle growth. This work highlights the importance of catalytic structure design for bimetallic catalysts in the selective hydrogenation of biomass-derived platform molecules and provides a strategy for synthesizing bimetallic catalysts.
