Controlled Synthesis of RuNi-CNTs Nano-Composites and Their Catalytic Performance in Benzene Hydrogenation

In this work, the Ni-X and Ni-CNTs-X (X = No, F, Cl, Br, or I) nano-composites are successfully synthesized via a simple hydrothermal synthesis method. The corresponding RuNi-X (or RuNi-CNTs-X) composites were prepared at room temperature by a simple galvanic replacement reaction. The morphologies of RuNi-CNTs were modulated by adding different halogen ions during the synthesis process. The RuNi-CNTs-X samples with various shapes showed distinct different catalytic performance in benzene hydrogenation. The change rule of the catalytic behaviors of the RuNi-CNTs-X catalysts was similar to that of RuNi-X. The order of the catalytic properties of RuNi-CNTs-X for benzene hydrogenation was RuNi-CNTs-F > RuNi-CNTs-No > RuNi-CNTs-Cl > RuNi-CNTs-Br > RuNi-CNTs-I.

Automated summary

In this study, Ni-X and Ni-CNTs-X (X = No, F, Cl, Br, or I) nano-composites were successfully synthesized using a simple hydrothermal synthesis method. RuNi-X (or RuNi-CNTs-X) composites were prepared through a galvanic replacement reaction at room temperature, with the morphology of RuNi-CNTs modulated by the addition of different halogen ions during synthesis. The RuNi-CNTs-X samples exhibited varied catalytic performance in benzene hydrogenation, with the order of catalytic properties being RuNi-CNTs-F > RuNi-CNTs-No > RuNi-CNTs-Cl > RuNi-CNTs-Br > RuNi-CNTs-I.
