? 2022 Elsevier B.V.Electronic structure regulation is one of the essential strategies for developing advanced electrocatalysts. Herein, FeOOH was electrodeposited on the surface of NiSe2/Ni2O3, resulting in a layered NiSe2/Ni2O3/FeOOH interfacial composite with a unique hierarchical structure and strong electronic interactions. This sheet-like nanostructure provides sufficient space for mass transfer, fully exposes the active sites, and accelerates the reaction kinetics. The optimal sample exhibits excellent oxygen evolution reaction (OER) activity with a low overpotential of 270 mV at a current density of 100 mA cm?2 and a Tafel slope of only 54.7 mV dec?1. It also has excellent durability. This study provides a new perspective for developing efficient electrocatalysts by constructing interfacial composites.
