Metal oxide nanoparticles have found numerous applications in different fields. In this paper, the preparation of nickel oxide nanostructures is given. The nanostructures were synthesized by using the hydrothermal method. The characterization was done with X-ray diffraction (XRD) and scanning electron microscopy (SEM). The newly synthesized nanostructures were utilized as a modifier of the working electrode, i.e., glassy carbon electrode (GCE). The modified GCE exhibited an excellent response towards methotrexate (MTX) anticancer drug. The modified GCE, as compared to bare GCE, showed an increased response towards MTX. In this study, BrittonRobinson buffer (BRB) was selected as a supporting electrolyte having pH 5. By using electrochemical impedance spectroscopy (EIS), the method was found linear in the range of 5-40 µM with a limit of detection and quantification values of 2.4 µM and 7.28 µM, respectively. The method developed by this way was successfully applied for the analysis of MTX from injection formulations. The interference studies were also carried out to check the method's selectivity.

Nickel oxide (NiO) nanostructures were synthesized by hydrothermal method using ethylene glycol and double distilled water as solvent in 3:2 volume ratio. The synthesized nanostructures were characterized by XRD, FESEM, EDX, FTIR, and UV-visible spectroscopy. XRD result shows that the synthesized nanostructures are polycrystalline in nature. FESEM images show the growth of NiO nanowires. The elemental compositions of the samples were analyzed by EDS. Fourier transform infrared (FTIR) spectroscopy confirms the existence of Ni–O bond in the sample. Optical band gap energy of about 3.71 eV was calculated from the UV-visible absorption measurement.

Good Crystallinity

Nickel oxide (NiO) nano-particles were produced via a simple microwave method from the Ni(OH)2 precursor, which was obtained by slow drop-wise addition of 0.1M sodium hydroxide to 0.1M nickel nitrate. The mixture was vigorously stirred until the pH reached 7.2. The mixture was then irradiated with microwave to deposit Ni(OH)2 at a better precipitation rate. Drying the precipitate at 320°C resulted in formation of NiO nanoparticles. High Resolution Transmission Electron Microscope (HRTEM), Scanning Electron Microscope (SEM) and X-ray diffraction (XRD), employed for the structural characterization of the as-prepared NiO nanoparticles, revealed their good crystallinity and high-purity. Microwave irradiation increased homogeneity and decreased the mean particle size of the produced NiO particles.
