ABSTRACT A nitrogen‐doped carbon‐supported Fe‐Fe3C‐Fe3O4 composite (Fe‐Fe3C‐Fe3O4@CN) has been synthesized through a one‐step pyrolysis of an iron‐based complex (Fe@tremella‐est), in alignment with the principles of surface organometallic chemistry (SOMC). The Fe@tremella‐est complex was synthesized through a straightforward chelation process using N‐containing alanine‐modified tremella (tremella‐est) as the raw material. This approach enhances the resulting catalyst by providing a large specific surface area, high dispersity, and an increased number of Fe‐N species. These distinctive advantages confer upon Fe‐Fe3C‐Fe3O4@CN a higher catalytic efficiency compared with traditional catalysts (Fe‐Fe3C@CN and Fe‐Fe3C@CN‐550), along with enhanced stability during recycling experiments. This SOMC strategy may serve as a new framework for the synthesis of biomass‐derived nanocatalysts for various catalytic reactions. High‐efficiency biomass‐derived Fe‐Fe3C‐Fe3O4 incorporated into carbon–nitrogen catalyst prepared via direct pyrolysis with N‐molecule‐assisted surface organometallic chemistry strategy for hydrogenation of nitroarenes to arylamines.
