General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency and is intended for Molecular Solar Thermal Energy Storage Systems (MOST). Click here for more information.

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).
