Abstract

Selective and efficient catalytic hydrogenation of aromatic nitro compounds with multiple groups into target amines under mild conditions is highly desirable yet fairly challenging. Herein, we report a novel iron-based catalyst, which has metal nanoparticles (NPs) encapsulated in porous N-doped carbon nanotubes (NCT). The experimental and density functional theory results reveal that the NCT-supported porous structure provides the metal nanoparticles with more accessible active sites, leading to the Fe/Fe 5 C 2 @NCT-800 catalyst to show extremely high activity, chemoselectivity, and stability toward the hydrogenation of nitro compounds, affording full conversion within 0.2–0.3 h under room temperature.
