Abstract
A method of electrode hydrogenation for photoelectrochemical (PEC) water oxidation is provided that includes annealing a PEC electrode in air, and annealing the PEC electrode in hydrogen to form a hydrogenated-PEC electrode, where PEC performance is improved by enhancing charge transfer and transport in the hydrogenated-PEC electrode.
