High-activity Ce–CoB porous electrocatalysts <i>via</i> cerium doping for superior OER performance
Ce-doped cobalt boride (Ce-CoB) was synthesized <i>via</i> a ZIF-67-derived boridation strategy, where Ce incorporation synergistically tunes the electronic structure to accelerate oxygen evolution kinetics. The Ce-CoB achieves an overpotential of 320 mV at 10 mA cm<sup>-2</sup>, outperforming benchmark CoB by 15.8% (<i>vs.</i> 350 mV) with remarkable robustness. These attributes position Ce-CoB as a scalable, high-efficiency OER catalyst for alkaline water electrolysis.
