Mechanism of Nickel–Iron Water Oxidation Electrocatalysts
WebMay 9, 2024 · An iron-oxidizing bacteria corrosion approach is developed to construct iron oxides top–down from iron-oxidizing bacteria corrosion integrated with nickel–iron oxyhydroxides to boost oxygen evolution. This study demonstrates a natural bacterial corrosion strategy to prepare highly efficient electrodes top–down for efficient water ... WebIron oxide (α-Fe2O3) films were formed at low substrate temperatures (250–350 °C), whereas the additional growth of an underlying NiO film occurred at substrate temperatures above 350 °C. The electrochemical activities of the as-formed binder-free and noble metal-free electrodes were tested for the oxygen evolution reaction (OER) in alkaline media.
