RuO2-based materials are considered an important kind of electrocatalysts on oxygen evolution reaction and water electrolysis, but the reported discrepancies activities exist among RuO2 prepared via different processes. Herein, a highly efficient catalysts facile hydrolysis-annealing approach is for electrolysis. The catalyst dealt with at 200 °C (RuO2-200) performs highest both (OER) hydrogen (HER) in acid overpotentials mV OER 66 HER to reach current density 100 mA cm-2 as well stable operation for100 h. high-resolution transmission electron microscopy (HRTEM) X-ray photoelectron spectroscopy (XPS) characterizations show that as-prepared rely hydroxide group/lattice (OH-/O2-) ratio, size, crystalline RuO2. functional theory (DFT) calculation also reveal OH- would enhance modifying electronic structure facilitate intermediate adsorption, thereby reducing energy barrier rate-determining step. electrolysis by using RuO2-200 anode cathode demonstrates generation high Faradic efficiency ≈30 potential below 1.47 V.
