The resultant solid product was characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), thermogravimetry (TGA), and FTIR techniques. Based on the obtained results, the formation of Bi2O3 nanoparticles and nanorods at lower and higher percentage of starch is promising. It was found that Bi2O3 nanorods catalyse the aromatization of 1,4-dihydropyridines (DHPs) with 100% conversion and 100% selectivity.
