<p>The reduction of nitroarenes is a critical process in organic synthesis and environmental remediation, yet traditional methods often suffer from low efficiency and catalyst leaching. This study presents a novel approach to enhance nitroarene reduction by developing a ZnFe₂O₄@EDTA nanocomposite for efficient nickel immobilization. The synthesized nanocomposite effectively integrates nickel nanoparticles onto a stable ZnFe₂O₄ support, utilizing ethylenediaminetetraacetic acid (EDTA) as a chelating agent to enhance metal dispersion and prevent leaching. Comprehensive characterization techniques, including XRD, TEM, SEM, EDX, BET, and FT-IR analysis, confirm the successful synthesis and functionalization of the nanocomposite. The catalytic performance of the immobilized nickel was evaluated in the reduction of various nitroarene substrates under mild conditions, demonstrating remarkable activity and selectivity. In addition, the nanocomposite exhibited excellent recyclability, retaining catalytic efficiency across multiple cycles without significant nickel leaching. This groundbreaking approach not only revitalizes the nitroarene reduction process but also paves the way for the development of more sustainable and efficient catalytic systems in organic transformations, providing a reliable and efficient method for future research and applications.</p> Graphical abstract <p></p>
