In the present study, peptide nanofiber was used to immobilize zinc oxide. This nanoparticle was prepared through self-assembly in an aqueous solution. The structural properties of the prepared catalyst were examined by a series of techniques, such as FT-IR, EDS, SEM, TEM, XRD, ICP-OES (inductively coupled plasma optical emission spectrometry), and ultraviolet–visible (UV–Vis) spectroscopy. TEM images showed the necklace model for peptide nanofiber decorated with zinc oxide. The versatility of the method was investigated by N-arylation using reaction of amines with hydroxybenzotriazole as a novel phenylating reagent, one-pot synthesis of imidazoheterocycles by a three-component reaction of 2-aminopyridine, aldehyde, terminal alkyne and preparation of tetracyclic quinazolinone ring by one-pot reaction of isatoic anhydride, amine, and ninhydrin. High yields, low cost of catalyst, environmental friendliness, efficient recovery and recyclability of catalyst are the most important features of this catalytic system.
