we develop a co-precipitation strategy to prepare an ultrathin NiCu layered double hydroxide (LDH) nanosheet arrays on carbon cloth (CC). As an advanced catalysts of oxygen evolution reaction (OER) with a three-dimensional nano-architecture, the as-prepared NiCu LDH/CC hybrids exhibit a remarkably small Tafel slope (ca. 42.5 mV dec−1), a low overpotential (ca.290 mV required for 10 mA cm−2), and a high stability with 90.6% activity retention after 5 h continuous polarization at 1.6 V vs RHE. Their superior OER performance surpasses that of the commercial IrO2/C, and can compete against that of state-of-the-art LDH electrocatalysts.
