 In this study, we developed a novel, cost-effective and eco-friendly magnetic nanocomposite of copper ferrite nanoparticles, CuFe2O4NPs, and carbon quantum dots, CQDs, of citric acid. This composite was synth-sized by coprecipitation and then used as a nanocatalyst to reduce nitroanolines, ortho-nitroanoline, ONA, and paranitroanoline, PNA, with sodium borohydride, NABH4. The catalytic activity of the nanocomposite was assessed through UVVS spectrophotometry, which indicated that it exhibited higher catalytic efficiency compared to CuFe2O4NPs. Furthermore, the results of X-ray diffraction, XRD, transmission electron microscopy, TEM, Bruner-Emmett-Teller, BET, surface area measurements, and Fourier transform infrared spectroscopy, FDIR, confirmed the formation of a well-dispersed nanocomposite with high crystallinity and uniform particle size distribution.
