Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The catalytic properties of catalysts are generally highly dependent on their nanostructures in most heterogeneous catalytic reactions. Therefore, to acquire targeted catalytic activity, selectivity, and stability, catalysts with a specific nanostructure should be designed and synthesized. Herein, Ru‐Ni bimetallic nanoparticles with different nanostructures, Ru‐Ni alloy, Ru@Ni, and Ru clusters‐on‐Ni on carbon, have been synthesized by annealing Ru‐Ni/C in flowing N₂+10 % H₂ at different temperatures. The various nanostructures of the Ru‐Ni bimetallic nanoparticles have been characterized and their catalytic behaviors were evaluated using benzene hydrogenation to cyclohexane. The relationship between the Ru‐Ni bimetallic nanostructures and their catalytic performance is presented. It was found that Ru‐Ni alloy/C and Ru clusters‐on‐Ni/C are much more active than Ru@Ni/C. This study also provides a simple method to design and control the nanostructures of the Ru‐Ni bimetallic nanoparticles.</p> </abstract>
