Nickel(II) Oxide (NiO) is a black or greenish-black inorganic compound that serves as an important material in various industrial applications. It is commonly utilized in battery manufacturing, where it plays a crucial role in the production of nickel-based batteries. Its fine particle size, typically −325 mesh (<44 μm), enhances its reactivity and performance in electrochemical applications. In addition to battery manufacturing, Nickel(II) oxide is also used in ceramics, supercapacitors, and as a catalyst in chemical reactions. Its versatility makes it valuable in various sectors, including electronics and materials science.

Application

  • Benchmarking Nanoparticulate Metal Oxide Electrocatalysts for the Alkaline Water Oxidation Reaction: This study evaluates the electrocatalytic performance of nickel oxide for water oxidation, important for material scientists working on energy conversion technologies (S Jung et al., 2016).
