Abstract

MoO₂/Ni_0.2Mo_0.8N interfacial nanorods on nickel foam (MONMN-NRs) were reported as an efficient electrocatalyst for the oxygen evolution reaction (OER) in alkaline media. The optimized catalyst delivered an ultralow overpotential of 264 mV@10 mA cm⁻² in 1.0 M KOH. The enhanced performance is mainly attributed to the strong electronic interaction between MoO₂ and Ni_0.2Mo_0.8N that facilitates the OER intermediates according to theoretical analysis.
