A 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.

Alkaline seawater electrolysis is fundamentally constrained by intrinsic trade-offs among oxygen evolution reaction (OER) activity, selectivity, and durability, arising from sluggish OER kinetics, parasitic chloride oxidation, and catalyst degradation. Here,...
