The Pt–Sn–B/carbon nanotubes (CNTs) catalyst was prepared by impregnation–chemical reduction method. Its catalytic performance was evaluated by liquid-phase hydrogenation of chloronitrobenzene (CNB). The results showed that the catalyst had higher catalytic performance than common hydrogenation catalysts. The conversion of CNB could reach 99.9%, and the dechlorination of chloroaniline (CAN) was less than 1.9% when catalyzed by Pt–Sn–B/CNTs and more than 8.0% when catalyzed by common hydrogenation catalysts. X-ray diffraction and selected area electron diffraction analysis showed that Pt–Sn–B/CNTs had an amorphous alloy structure that can improve catalytic performance. Transmission electron micrograph image showed that the catalyst particles were highly distributed on the surface of CNTs. The hydrodechlorination of CNB was mainly affected by the unique structure of CNTs and the nature of the amorphous metals on the surface of CNTs. The relationship between the interaction of CNTs and amorphous metals and the catalytic performance of the catalyst is also discussed. |
