Abstract
Supercapacitors, Li-ion batteries, gas sensors, and electrochromic devices are expected to play a major role in the development of sustainable technologies. Recent progress has demonstrated that nanostructured nickel oxides are very promising candidates for efficient energy conversion and storage systems. Recently, there is a growing interest in nickel oxide nanoparticles due to their unique physical and chemical properties. In this work, the synthesis of nickel oxide nanoparticles is primarily categorized with the preparation method. This review also provides a comparative overview of the influence of technological conditions on the properties of nickel oxide nanoparticles.

This review provides a comparative overview of the influence of technological conditions on the properties of nickel oxide nanoparticles
NiO nanoparticles with different sizes were synthesized in the presence of various nickel salts and the impact of anions on the magnetic properties was investigated [22]
Summary
Among transition metal oxides nickel oxide (NiO) nanostructures have attracted much attention owing to their unique optical, electrical, catalytic, and magnetic properties. It is a promising candidate for a wide range of applications like gas sensors, supercapacitor, anode material for Li-ion batteries, catalyst, dye-sensitized photocathodes, optoelectronic devices etc. Flower-like NiO microspheres exhibited maximum adsorption capacity (535 mg g−1) in comparison to other adsorbents for CR [8]. Nanostructured NiO exhibits electronic, dielectric behavior and high reversible capability because of quantum size confinement and high surface energy. We could get more information about nanostructured nickel oxide, its basic synthesis techniques and applications in many fields
