Photocatalytic Activity of Nickel Oxide

Journal of Materials Research and Technology, 2019
In this work, synthesis of nickel oxide (NiO) using nickel acetate as a starting material by sol–gel method and then deposited as collide on glass slides to form thin layers of NiO by spin-coating technique with high photo-catalytic activity using as self cleaning coating. These films of NiO were annealed at different temperature 450 °C, 550 °C.
