Nickel oxide (NiO) is a p-type wide bandgap semiconductor and transition metal oxide with cubic lattice structure. It has attracted increasing attention owing to potential use in a variety of applications such as: catalysis, battery electrodes, gas sensors, electrochromic films, magnetic materials, photo-electron devices, ion storage materials, thermoelectric materials, supercapacitors, fuel cells, anticancer properties, cytotoxic activity and sensors.
Various synthesis methods such as pulsed laser ablation, microemulsion-assisted synthesis, spray pyrolysis, ball milling, chemical vapor deposition, gas deposition, radiolytic reduction, sonochemical method, chemical precipitation, hydrothermal method, sol-gel method and electrospinning were adopted to NiO nanoparticles. Hydrothermal method is preferred due to relatively easy control over production parameters, particle size distribution, morphology and chemical composition. In the hydrothermal method, many anionic, non-ionic and cationic additives can often be used. These types of additives can affect the properties of the NiO nanostructures. However, there are not enough studies on the effect of these additives. In this study, NiO nanoparticles were synthesized via the hydrothermal method using different additives (NaOH, HMT, urea, and PVP) to investigate their effects on the NiO nanostructure. The NiO nanomaterials were characterized using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and UV-Visible spectroscopy.
The results demonstrated that various additives have significant effect on NiO morphology.
