Due to their porous and hollow nanostructures, and synergetic effects between their components, the optimized nickel cobalt oxide nanosponges exhibited excellent catalytic activity towards oxygen evolution reaction.enghttps://creativecommons.org/licenses/by/3.0/540cobaltmetal nanoparticlenanocompositenanomaterialnickeloxidesodium borohydrideaqueous solutioncatalystoxygen evolutionporositypotentiometryreaction analysissynthesisArticle
