Abstract	The exploration of highly efficient and stable non-noble metal electrocatalysts for oxygen evolution reaction (OER) is a crucial challenge. Herein, we demonstrate the design and fabrication of three-dimensional (3D) gallium-doped FeOOH/NiS nanosheet arrays on a Ni foam (denoted as FeOOH/Ga-NiS) via a facile hydrothermal synthesis and their subsequent electrodeposition. Benefiting from the strong interfacial coupling effects between FeOOH and NiS, Ga doping in NiS creates exposed active sites, and the optimal 3D FeOOH/Ga-NiS electrocatalyst exhibits outstanding electrocatalytic performance towards OER, while requiring a low overpotential of 274 mV at 100 mA cm. In addition, it possesses impressive durability of up to 24 h even at 100 mA cm. Furthermore, density functional theory (DFT) calculations validate the improved conductivity and binding energy of oxygen-containing intermediates due to synergistic effects among multiple components and the optimised electronic structure of NiS ascribed to Ga doping, which boosts the OER performance. This study provides new insight into the fabrication of highly active, stable, and cost-effective electrocatalysts.
