摘要
An in situ electrochemical strategy is developed to convert semiconductive beta-FeOOH to OER-active semi-metallic Ni incorporated beta-FeOOH. The sample exhibits an overpotential of 247 mV at 10 mA cm(-2), which is much lower than those of pure beta-FeOOH (400 mV) and RuO2 (258 mV). This strategy is also suitable for incorporating Ni into gamma-FeOOH and CoOOH with enhanced OER activities.
