ABSTRACTVisible (λ > 420 nm) light-driven photooxidation of water at TiO2-polyheptazine (TiO2-PH) hybrid photoanodes loaded with two different metal oxide co-catalysts was investigated in a twoelectrode setup. As compared to TiO2-PH photoanodes loaded with colloidal IrO2, photoelectrodes modified with photodeposited CoOx oxygen-evolving co-catalyst (Co-Pi) showed both higher photocurrents and more efficient oxygen evolution. The minimum external electric bias needed to observe complete photooxidation of water to dioxygen at TiO2-PH photoanodes modified with Co-Pi was estimated to be ca. 0.6 V at pH 7.
