Abstract
β-Ni(OH)<sub>2</sub> on Ni foam can be synthesized using a hydrothermal method. The addition of Fe<sup>3+</sup> during synthesis produced Fe-doped α-Ni(OH)<sub>2</sub> at 120 °C and Fe-doped β-Ni(OH)<sub>2</sub> at 240 °C. The HER and OER activity of these materials were investigated through both experiment and DFT.
