α-Fe2O3 on patterned fluorine doped tin oxide for efficient photoelectrochemical water splitting

Abstract

Patterned FTO was fabricated via a facile method as an efficient current collector in a photoelectrochemical water splitting system. The photocurrent density of α-Fe₂O₃ on patterned FTO exhibited a 1.7 times increase relative to α-Fe₂O₃ on FTO due to the light scattering and rapid transfer of excited electrons.
