FeO-Based Hierarchical Structures on FTO Substrates and Their Photocurrent.

ABSTRACT: As one of the most promising photoanode materials for photoelectrochemical (PEC) water oxidation, earth-abundant hematite has been severely restricted by its poor electrical conductivity, poor charge separation, and sluggish oxygen evolution reaction kinetics. FeO has an ability to produce hydrogen, while its preparation needs high temperature to reduce Fe³⁺ to Fe²⁺ by using H₂ or CO gases. Here, Fe₂O₃- and FeO-based nanorods (NRs) on fluorine-doped tin oxide (FTO) substrate have been prepared, where the latter was obtained by doping Sn⁴⁺ ions in FeOOH to reduce Fe³⁺ ions to Fe²⁺. X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) measurements indicate that the dominant content of Fe ele
