Abstract

ABSTRACTBiOCl/FeOCl nanorods composited by SiO2 spherical nanoparticles as a novel nanocatalyst and also it has been synthesized using a co-precipitation procedure. Additionally, its structural along with the catalyst activity have been determined by transmission electron microscopy, scanning electron microscopy, X-ray diffraction, energy dispersive X-ray spectroscopy, as well as Fourier transforminfrared spectroscopy. In addition, this nanocomposite was utilized efficiently in the synthesis of 2-arylbenzimidazole derivatives, which is described by the condensation of some aldehydes and o-phenylenediamines in the presence of BiOCl/FeOCl/SiO2 nanocomposite as a novel nanocatalyst. Besides the investigated variables such as the amount of catalyst, reaction temperature, the synergistic effect of BiOCl and FeOCl, and effect of various solvents, the possible reusability of the catalyst is also studied. In conclusion, the synthesized BiOCl/FeOCl/SiO2 nanocomposite has several remarkable advantages like non-toxic nanocatalyst, has a recovering and recycling for three runs minimally without a significant loss of catalytic activity under the aerobic mild condition, short reaction times, and being solvent-free.
