General description

Nickel(II) oxide (NiO) is a metal oxide based nanomaterial with a good semiconducting property. Nanosized nickel oxide can be found in a variety of morphologies which include nanoflowers, spheres, wires, and tubes. It exhibits high performance in applications which require charge transfer and charge transport based processes. It can be prepared by a variety of physical and thermal methods such as sol-gel, hydrothermal and solvothermal techniques.
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.

Application

NiO can be used for a variety for energy and coating based applications such as lithium ion batteries, solar cells, electrochromic coatings, semiconducting films, and gas based sensors.
