Compact hematite buffer layer as a promoter of nanorod photoanode performances

The effect of a thin α-Fe(2)O(3) compact buffer layer (BL) on the photoelectrochemical performances of a bare α-Fe(2)O(3) nanorods photoanode is investigated. The BL is prepared through a simple spray deposition onto a fluorine-doped tin oxide (FTO) conducting glass substrate before the growth of a...

description The effect of a thin α-Fe(2)O(3) compact buffer layer (BL) on the photoelectrochemical performances of a bare α-Fe(2)O(3) nanorods photoanode is investigated. The BL is prepared through a simple spray deposition onto a fluorine-doped tin oxide (FTO) conducting glass substrate before the growth of a α-Fe(2)O(3) nanorods via a hydrothermal process. Insertion of the hematite BL between the FTO and the nanorods markedly enhances the generated photocurrent, by limiting undesired losses of photogenerated charges at the FTO||electrolyte interface. The proposed approach warrants a marked improvement of material performances, with no additional thermal treatment and no use/dispersion of rare or toxic species, in agreement with the principles of green chemistry.
