摘要

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. ? 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
