Abstract
Three dimensional (3D) nickel oxide/nickel (NiOx/Ni) structure has been synthesized through a facile in situ electro-oxidation method. The formation of NiOx through the electro-oxidation process has been proved by \SEM\ and EDX, with some dense black dots appearing on the surface of Ni foam and the molar ratio of O/Ni increasing, which is nearly 7 times larger than the pure Ni foam. The increase in O content indicates the formatted black particles on the surface of Ni foam are composed of NiOx. The electrocatalytic property of the obtained 3D NiOx/Ni structure has been measured and it can be used as a highly active electrocatalyst for oxygen evolution reaction (OER). The overpotential to reach j = 10 mA cm?2 is 0.39 V. And after the long-term I
