A green, efficient methodolgy was developed for the synthesis of ZnO nanoparticles in aqueous ethanol media in the presence of microwave irradiation. The in-house synthesized ZnO was used for the synthesis of 1,4-dihydropyridines. The target molecules were obtained in good to excellent yield applying the current method. After completion of the reaction we extracted the ZnO catalyst characterized by powder XRD and SEM analysis. The result indicates that no such change was observed in powder XRD but there is a remarkable change in the ZnO morphology. Further we repeated the similar experiment to know the catalytic behavior and its frequently changes in the ZnO nanoparticles. These results show that the reused crystalline ZnO morphology was changed and its particle size also increases. These factors influence on the catalytic activity, time and yield of the product. © 2020 World Research Association. All rights reserved.
