Abstract

n

nA straightforward and cost-effective method was employed to synthesize zinc oxide (ZnO) nanostructures supported on tin oxide (SnO₂) for catalytic applications. This hybrid nanocomposite, formed by integrating ZnO with SnO₂, exhibited impressive catalytic activity in the reduction of various nitro compounds. The synergistic interaction between ZnO and SnO₂ significantly enhanced the surface area and active sites of the catalyst, thereby improving its overall efficiency. The resulting SnO₂-ZnO nanocomposite not only exhibited exceptional catalytic reactivity but also showcased excellent stability over multiple cycles, along with remarkable reusability, making it highly practical for long-term applications. Its consistent performance without significant loss of activity highlights its robustness under reaction conditions. Owing to these advantageous features, the SnO₂-ZnO nanocomposite emerges as a highly promising and eco-friendly catalyst for the efficient transformation of toxic nitro compounds into valuable amine derivatives. Such a conversion is crucial in both environmental remediation and the synthesis of pharmaceuticals, dyes, and agrochemicals, where clean and sustainable chemical processes are increasingly in demand. This research study creates a way to explore the strength of mixed metal oxide composite material in the catalytic reduction of aromatic nitro compounds.it was observed that the reduction of nitro compounds takes place at faster rate with increasing the yield of products as compared to the traditional reducing agents like NaBH 4 .the surface morphology of synthesized mixed SnO 2 -ZnO composite was studied with the help of scanning electron microscopy by using WDS (JEOL Japan Model : JSM7600 F. kinetics of catalytic reduction process of nitro substituted aromatic compound’s was studied with he help of UV spectrophotometer.nn
