This study investigates the preparation of Ni/ZnO nanomaterials by facile co-precipitation (CPM) and hydrothermal (HTM) methods. The effect of the synthesis methods on the optical, structural, chemical and morphological properties of ZnO products is investigated using ultra violet (UV)-visible spectroscopy, X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectrometry (EDX), room temperature photoluminescence (PL), fourier transform infrared (FTIR) and Raman spectroscopy. Finally, the electrochemical performance of the synthesized nanorods was examined by the fabrication of a supercapacitor using standard three electrode cell configurations and tested with a cyclic voltammogram (CV) and galvanostatic charge-discharge (GCD) measurements. The results showed that the samples synthesized by HTM exhibited improved electrochemical capacitance performance with higher current density. The discharge curves are linear in the total range of potential with constant slopes, showing perfect capacitance. In conclusion, Ni/ZnO nanoparticles synthesized by this method with further optimization have the potential to lead to high-efficiency supercapacitors.\n\n{{Pearce publications notice}}\n\n== Keywords ==\n\n zinc oxide, Ni doped ZnO, co precipitation method, hydrothermal synthesis, electro-chemical performance\n\n== See also ==\n\n* [[Preparation of meta-stable phases of barium titanate by sol-hydrothermal method]]\n* [[Structural and optical characterization and efficacy of hydrothermal synthesized Cu and Ag doped zinc oxide nanoplate bactericides]]\n* [[Inhibition of growth of S. epidermidis by hydrothermally synthesized ZnO nanoplates]]\n\n{{Page data\n| license = CC-BY-SA-3.0\n| title-tag = Synthetic Method Dependent Physicochemical Properties of Ni-Doped ZnO\n| description = Appropedia reviews Ni-doped ZnO nanostructures, showing how synthesis methods impact energy performance and sustainable material applications.\n}}\n\n[[Category:MOST completed projects and publications]]\n[[Category:Materials processing]]\n[[Category:materials science]]\n[[Category:science]]"}
