scanning electron microscopy, and X‐ray photoelectron spectroscopy analysis. The heterogeneous nanocomposite has been used for one‐potsynthesis of various N‐heterocyclic compounds like pyrazoles, 1,2‐disubstituted benzimidazoles, 2‐arylbenzazoles, and 2,3‐dihydroquinazolin‐4(1H)‐ones under green reaction medium at room temperature. This novel method has several advantages, such as short reaction time, simple
