In this study, SO3H@zeolite-Y was synthesized by the reaction of chlorosulfonic acid with zeolite-NaY under solvent-free conditions, which was then supported by Fe3O4 nanoparticles to give SO3H@zeolite-Y (Fe3O4/SO3H@zeolite-Y) magnetic nanoparticles. Several techniques were used to evaluate the physical and chemical characterizations of the zeolitic nanostructures. Fe3O4-loaded sulfonated zeolite was applied as a novel multi-functional zeolite catalyst for the synthesis of imidazole and perimidine derivatives. This efficient methodology has some advantages such as good to excellent yield, high purity of products, reusability of nanocatalyst, simple reaction conditions, environmental friendliness and an economical chemical procedure from the viewpoint of green chemistry.

A stable nickel-decorated SBA-15 nanocomposite (Ni/TCH@SBA-15) was synthesized through surface modification of silica nanoparticles with 3-chloropropyltriethoxysilane (CPTES) and thiocarbohydrazide (TCH) followed by metal–ligand coordination with Ni (II). The structure of this organometallic nanocomposite was characterized by Fourier transform-infrared, field emission-scanning electron microscopy, EDAX, transmission electron microscopy, atomic absorption spectroscopy and N2 adsorption–desorption (Brunauer–Emmett–Teller) techniques. The catalytic performance of Ni/TCH@SBA-15 (NNTS-15) was determined for the synthesis of 2-aryl-substituted benzimidazoles and 2,3-dihydroperimidines. The excellent yields within shorter reaction times, simplicity of catalytic methods, non-toxicity and clean reactions, mild reaction conditions and easy work-up procedure are the important merits of these synthetic protocols. Moreover, the Ni (II) bonded to the SBA-15 surface was stable under the catalytic reaction conditions resulting in its efficient recycling and reuse.
