Cobalt-doped hematite thin films for electrocatalytic water oxidation in highly acidic media

Earth-abundant cobalt-doped hematite thin-film electrocatalysts were explored for acidic water oxidation. The strategically doped hematite produced a stable geometric current density of 10 mA cm −2 for up to 50 h at pH 0.3, as a result of Co-enhanced intrinsic catalytic activity and charge transport...
