Enhanced photoelectrochemical water splitting performance of α-Fe₂O₃ photoanodes through Co-modification with Co single atoms and g-C₃N₄.

ABSTRACT: The practical application of α-Fe₂O₃ in water splitting is hindered by significant charge recombination and slow water oxidation. To address this issue, a CoSAs-g-C₃N₄/Fe₂O₃ (CoSAs: cobalt single atoms) photoanode was fabricated in this study through the co-modification of CoSAs and g-C₃N₄ to enhance photoelectrochemical (PEC) water splitting. The coupling between g-C₃N₄ and α-Fe₂O₃ resulted in the formation of a heterojunction, which provided a strong built-in electric field and an additional driving force to mitigate charge recombination. Moreover, g-C₃N₄ served as a suitable carrier for single atoms, which effectively anchored CoSAs th
