The Pd/Fe@N/C catalyst showed the best catalytic activity under mild reaction conditions of 0.8 MPa H2 and 40°C, achieving >99% nitrobenzene conversion and 99% aniline selectivity. Many halogen-substituted and aliphatic nitro compounds have been studied, and target products with excellent selectivity have been obtained. As the catalyst has magnetic properties and is easy to separate, the flow reactor process is considered for further exploration in the later stage. The excellent mass and heat transfer performance of the continuous flow process will further make the reaction conditions milder, and strive to achieve the conversion at room temperature.
