Nickel(II) oxide is the chemical compound with the formula NiO. It is the principal oxide of nickel.Nickel Monoxide is a green to black colored, inorganic compound that turns yellow and produces toxic gases upon heating.
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
