The amino acid arginine was used to modify the surface of graphene oxide nanosheets and then nickel‐substituted cobalt ferrite nanoparticles were supported on those arginine‐grafted graphene oxide nanosheets (Ni 0.5 Co 0.5 Fe 2 O 4 @Arg–GO). The prepared Ni 0.5 Co 0.5 Fe 2 O 4 @Arg–GO was characterized using flame atomic absorption spectroscopy, inductively coupled plasma optical emission spectrometry, energy‐dispersive spectroscopy, Fourier transform infrared spectroscopy, ultraviolet–visible spectroscopy, Raman spectroscopy, X‐ray diffraction, thermogravimetric analysis, scanning electron microscopy and transmission electron microscopy. The application of Ni 0.5 Co 0.5 Fe 2 O 4 @Arg–GO as a catalyst was examined in a one‐pot tandem oxidative cyclization of primary alcohols with o ‐phenylenediamine to benzimidazoles under aerobic oxidation conditions. The results showed that 2‐phenylbenzimidazole derivatives were successfully achieved using Ni 0.5 Co 0.5 Fe 2 O 4 @Arg–GO nanocomposite catalyst via the one‐pot tandem oxidative cyclization strategy.
