This work not only determines the active sites of Fe for hydrogenation (FeN 4), but also proposes tentative pathways for both N-H activation of hydrazine and the reduction of nitroarene on FeN 4 site, both of which are the key steps for the hydrogenation of nitroarenes. Based on high-angle annular dark field scanning transmission microscopy (HAADF-STEM) images in combination with X-ray photoelectron spectroscopy (XPS), X-ray absorption spectroscopy (XAS), electron spin resonance (ESR), and Mössbauer spectroscopy, Fe is dispersed as single atoms via forming FeN x ( x = 4–6). The as-synthesized catalyst exhibits better performance on the chemoselective hydrogenation of nitroarenes with a broad substrate scope (turnover frequency (TOF) up to 1,727 h −1, 23 examples) than most of previously reported works. A facile, gram-scale and sustainable approach has been established for the synthesis of single-atomic-site iron on N-doped carbon (Fe via the pyrolysis of aniline modified FeZn-ZIFs, in which the synthesis of zeolitic imidazolate frameworks (ZIFs) can be accomplished in water at room temperature, and no acid etching is required.
