Carbon nanotube‐supported bimetallic Pt–Fe catalysts for nitrobenzene hydrogenation

Abstract

Carbon nanotube (CNT)‐supported Pt–Fe catalysts were prepared by a chemical reduction method using chloroplatinic acid and ferric nitrate as starting materials. The structure and the morphology of the catalysts were characterised by an X‐ray diffractometer, transmission electron microscopy and inductively coupled plasma atomic emission spectrometry. The catalytic performance for nitrobenzene hydrogenation was evaluated under atmospheric pressure at an ambient temperature. The bimetallic Pt–Fe/CNT catalysts showed much higher activity than Pt/CNTs with a similar Pt content for nitrobenzene hydrogenation.
