Jeung Ku Kang and his team describe innovative electrocatalysts grown on a three-dimensional conductive and porous electrode without the use of binders. These catalysts, featuring ultrafine metallic nickel domains and reduced molybdenum states, exhibit remarkable oxygen evolution activity, surpassing bare NiFe catalysts by approximately 60-fold. They also demonstrate long cycle stability and high faradaic efficiency over 95%, marking a significant advancement in electrocatalysis.-Scientific Journal cover design by scapiens
