Synthesis and Structural Characterizations of ZnO @ NiO Nanocomposite

Abstract Nanocomposites offer a wide range of versatile applications in the fields of nanotechnology and material science due to their unique combination of properties arising from the synergistic interaction between different nanoscale components. In this study, a ZnO@NiO nanocomposite was successfully synthesized using the co-precipitation method and its structural properties were comprehensively characterized. The surface morphology analyzed through scanning electron microscopy (SEM) revealed a highly porous and agglomerated structure with embedded rod-like and plate-like crystallites, indicating good interfacial interaction between ZnO and NiO phases. Energy-dispersive X-ray spectroscopy (EDX) confirmed the elemental composition, with nickel as the dominant element (77.48 at. %), followed by zinc (12.56 at. %) and oxygen (9.96 at. %), supporting the formation of a NiO-rich composite. The X-ray diffraction (XRD) pattern showed distinct and sharp peaks corresponding to hexagonal ZnO (JCPDS Card No. 36-1451) and cubic NiO (JCPDS Card No. 47-1049), with prominent reflections from ZnO planes such as (100), (002), and (101), and NiO planes like (111), (200), and (220), confirming the high crystallinity and phase purity of the nanocomposite. The successful integration of ZnO and NiO at the nanoscale with well-defined crystal structures suggests potential for applications in gas sensing, catalysis, and electronic devices.
