249. Octahedral-coordinated Co3O4 for water electrolysis in acid
Nature, Published online: 29 July 2026; doi:10.1038/s41586-026-10851-7A new trigonal-phase Co3O4 manufactured using a vacuum-mediated molten-alkali mechanochemical method is described, demonstrating edge-shared octahedral coordination and achieving lower overpotential than spinel-type Co3O4 in the acidic oxygen evolution reaction, with reduced dissolution of cobalt.
