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.

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.
