Abstract


Magnetic Ag–Co and Ag–Ni alloy nanoparticles were prepared through a chemical reduction method using their corresponding [Co(NH3)6]Cl3 and [Ni(C2O4)2]K2 complexes, and AgNO3. In this reaction, hydrazine monohydrate was used as reducing agent. The obtained nanoparticles were characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), and vibrating sample magnetometer (VSM). Ag–Co and Ag–Ni nanoalloys exhibited excellent catalytic performance in the preparation of 1,8–dioxooctahydroxanthenes from the reaction of 5,5-dimethyl-1,3-cycloheanedione (dimedone) with aromatic aldehydes. Catalysts were separated by an external permanent magnet and reused. Both, Ag–Co and Ag–Ni nanoalloys posess antibacterial and antioxidant properties and have no significant effect on DNA cleavage.
