A rational way to explore economically feasible high-performance electrocatalyst for OER is developed by improving the reaction kinetics of rate-determining step via the hybridization with electron-withdrawing RuO2 nanosheet. Even with very low RuO2 content, self-assembled Ni–Fe-/Ni–Co-layered double hydroxide (LDH)–RuO2 nanohybrids show very small overpotentials of 207/276 mV at 10 mA cm−2 for oxygen evolution reaction with greatly improved current densities.
