Preparation of Fe2O3/CC catalyst and its catalytic reduction performance of o-bromonitrobenzene

Abstract

o-Bromoaniline, as an important organic chemical raw material and intermediate, is widely used in the synthesis of pharmaceuticals, pesticides, dyes and functionalized polymers. There is an urgent need to develop green and efficient alternatives to traditional production methods due to high energy consumption, high pollution and poor catalyst stability. In this study, the Fe2O3/CC composite catalyst was innovatively prepared by using carbon cloth (CC) as a carrier combined with the activity of iron oxide (Fe2O3), and systematically evaluated in the multiphase catalytic reduction reaction of o-bromonitrobenzene. The experiments showed that the Fe2O3/CC catalysts possessed excellent catalytic activity and cyclic stability, and their catalytic efficiency did not decrease significantly after multiple recycling. In addition, the significant effect of hydrothermal temperature on the morphology and performance of the catalyst provided a new idea to optimize the catalyst performance. This study provides a new method for the green synthesis of o-bromoaniline and lays a theoretical foundation for the development of environmentally friendly and efficient catalysts in organic synthesis.
