Abstract Reduction of nitroarenes was achieved using magnetically separable and reusable iron oxide nanoparticles (Fe 3 O 4 @ RA NPs) Rhododendron arboreum ( ) flower extract with high yields in water hydrazine hydrate as a green hydrogen source. The synthesis the biogenic NPs has been done tools displays excellent magnetic properties, which have proved by vibrating sample magnetometry (VSM). Further, field‐emission scanning electron microscopy (FE‐SEM), Fourier transform infrared spectroscopy (FTIR), energy dispersive X‐ray (EDX), diffraction (XRD), photoelectron (XPS), thermogravimetric analysis (TGA), Brunauer–Emmett–Teller (BET), used for characterization synthesized Fe NPs. TEM XRD revealed crystalline nature size 10.8 nm. BET surface area total pore volume were observed 147.098 m 2 /g 0.323837 cc/g, respectively. VSM displayed super paramagnetic behavior hence reused up to six consecutive cycles without compromising its catalytic performance, further approved FTIR recycled Wide substrate scope functional groups tolerance, large‐scale reactions (up 1 g), key pharmaceutical drug, paracetamol, are some adding points
