title: Enhanced Photoelectrochemical Oxygen Evolution Reaction Ability of Iron-Derived Hematite Photoanode with Titanium Modification.
abstract: A facile fabrication route towards a titanium-modified hematite photoanode has been developed, and the photoelectrochemical properties of this anode have been evaluated. Compared to pristine hematite, the activity of the modified photoanode in this work delivered almost twofold higher photocurrent under Air Mass 1.5G illumination. Further research revealed that the enhanced performance of the hematite photoanode with a titanium-modified surface resulted from the dominant impact of heterojunction formation and suppressed surface recombination, supplemented by a slightly improved light-harnessing ability.
