Abstract: The islands like barium aluminum oxide BaAl₂O₄ nano-spheres were grown on the surface of Al₂O₃-MgO composite via oil in water (O/W) micro-emulsion method. Hexane, 2-aminoethanol and ethanol were used as oil phase, non-anionic surfactant and co-surfactant respectively. The synthesized Ba Al₂O₄ nano-spheres were grown on the surface of Al₂O₃-MgO composite and have been characterized using X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and Energy-dispersive X-ray spectroscopy (EDAX). The BaAl₂O₄ nano-spheres grown on the surface of Al₂O₃-MgO composite exhibited high catalytic activity for the transformation of cinnamaldehyde, methyl/ethyl acetoacetate and aromatic amines as the starting materials to 1,4-dihydropyridine derivatives.
