Abstract
Exploring electrocatalysts that possess both high activity and long-term durability is essential for the practical implementation of seawater electrolysis; however, achieving this goal remains a major bottleneck. Herein, a spin engineering strategy is proposed for antiperovskite nitride (CuNNi3–xMox) to boost its inherent catalytic activity. The partial substitution of Ni sites with Mo atoms induces a transition from low-spin state Ni2+ (eg2 t2g6) to high-spin state Ni3+(eg2 t2g5). The Mo-substituted catalyst exhibits superior electrocatalytic performance, yielding low overpotentials of 212 mV for the hydrogen evolution reaction (HER) and 453 mV for the oxygen evolution reaction (OER) at a current density of…
