## Abstract

Reducing nitroarenes to aromatic amines is a valuable method in both industrial and synthetic organic chemistry for producing amine compounds. Recently, magnetite‐based nanocatalysts have attracted attention as promising, eco‐friendly alternatives to conventional noble‐metal catalysts in this transformation. Magnetite nanoparticles, with their large surface area, strong catalytic performance, and inherent magnetic properties, enable easy separation and reuse, significantly supporting the sustainability of the process. Fe3O4@graphene oxide nanocatalysts are regarded as highly promising due to their straightforward synthesis, affordability, excellent superparamagnetic behavior, good biocompatibility, and low toxicity. Utilizing environmentally friendly reducing agents such as sodium borohydride or H2, alongside these adaptable nanocatalysts, enables fast and selective transformation of nitroarenes under moderate reaction conditions. This study emphasizes the promise of Fe3O4@graphene oxide magnetic nanocatalysts as an economical, recyclable, and environmentally friendly catalyst for the hydrogenation of nitroarenes, offering a valuable approach toward a more sustainable chemical industry. This review provides an overview of the synthesis and applications of Fe3O4@graphene oxide magnetic nanocatalysts, highlighting their effectiveness and eco‐friendliness in the hydrogenation of nitro compounds, with coverage extending through 2025.

This review provides a comprehensive summary of recent advances in Fe3O4@graphene oxide magnetic nanocatalysts for the reduction of nitroarenes. The reduction of nitroarenes yields valuable intermediates that serve as key building blocks in the synthesis of agrochemicals and pharmaceuticals. Fe3O4@graphene oxide magnetic nanocatalysts are expected to enable the industrial removal of hazardous nitro compounds in the future.© 2026 WILEY‐VCH GmbH
