Abstract

Abstract: In this paper, we have developed a new branch of multifunctional iron tin oxide composite as an efficient catalyst for the reduction of the nitroarenes. The iron‐tin bimetallic oxide nanoparticles anchored on the carrier of carbon nanospheres synthesized by hydrothermal carbonization (HTC) were the active sites. And in the presence of the multi‐component catalyst C@Fe2O3‐SnO2, the nitroaromatics were quantitatively converted into aromatic amines with the hydrogen source of hydrazine hydrate. The synergy interaction between the two kinds of metallic oxides provided a certain enhancement for the catalytic activity of iron based catalyst. Moreover, these nanocatalysts could be collected through magnetic separation, and recycled for 10 times without any loss of catalytic activity. These results showed that the catalyst system possessed the superiority of wide application scope, safety, high efficiency and good chemoselectivity. Abstract : A carbon‐supported multifunctional iron‐tin oxide catalyst was prepared for the reduction of aryl nitro compound. The catalyst is very stable and can be recycled more than ten times without any loss and easily collected by magnetic separation. Synergy between two metallic oxides greatly enhances the catalytic reactivity.
