Catalyzing overall water splitting at an ultralow cell voltage of 1.42 V via coupled Co-doped NiO nanosheets with carbon

A hybrid structure constructed by Co-doped NiO and carbon on nickel foams could be employed as bifunctional electrocatalyst for both anode and cathode towards overall water splitting, enabling an alkaline electrolyzer with a current density of 10 mA cm−2 at an ultralow cell voltage of 1.42 V.
