Introduction: The preparation and exploration of catalytic activity of nanoparticles
in organic transformations have become a genuine need of clean and sustainable
chemistry if they are non-toxic, readily available, and recyclable.
Experimental: Nanoparticles show the unusual or enhanced properties due to their nanosize
and high surface to volume ratio. In this paper, Nanocrystalline CoFe2O4, a wellknown
magnetic compound was prepared by glycine-nitrate combustion route. X-ray
Diffraction (XRD) and Transmission Electron Microscope (TEM) confirmed the formation
of single-phasic cobalt ferrite nanoparticles.
Result: The crystallite size was found to be 46 nm. BET study showed the surface area
24.2 m2/g. The catalytic behavior of as-prepared nanoparticles was studied in the synthesis
of benzimidazole derivatives. Various benzimidazole derivatives have been prepared
in moderate to good yield in facile one-pot synthesis under mild conditions using magnetically
Conclusion: The catalyst is found to be green, efficient and economically viable.
