Abstract

The CoFe2O4 with various morphologies has been successfully synthesized via ionic liquid-assisted hydrothermal synthetic process and was used as a catalyst to form imidazo[1,2-a]pyridines. The structural and magnetic properties of the catalyst were characterized by X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM), nitrogen sorption techniques (BET), and vibrating sample magnetometer (VSM). The results indicate that the samples are nanoparticles, nanorods, and nanosheets which clearly shows the effect of octyl-4-aza-1-azoniabicyclo[2.2.2]octane bromide ([C8dabco]Br) ionic liquid on the morphology of final products. According to the SEM and magnetic hysteresis measurements, different ratios of [C8dabco]Br resulted in different morphologies and crystalline sizes and hence different magnetic properties in the synthesized materials. Textural analysis by N2 sorption revealed that the total BET surface areas of CoFe2O4 nano powders were 23.5–48.6 m2/g. It was found that the values of remanent magnetization (Mr) and saturation magnetization (Ms) increase with increment of IL ratio. Moreover, the reaction of aldehydes, 2-aminopyridines, and isocyanide was carried out under solvent-free conditions by cobalt ferrite as a suitable catalyst, and all desired products were formed in good yields. The ultraviolet (UV) spectrum has been used to calculate the absorption coefficient (α) as a function of photon energy (hυ), and the obtained results indicate that the optical band gaps are estimated to be 1.23–1.38 eV.
