Crystallinity Engineering of Hematite Nanorods for High-Effi ciency Photoelectrochemical Water Splitting

---

Photoelectrochemical (PEC) water splitting holds great promise for sustainable energy by harvesting solar energy. In particular,hematite (α-Fe 2 O 3 ) has been extensively investigated as a photoanode for visible light-driven PEC water splitting due to its availability, stability, and suitable bandgap of 1.9–2.2 eV. [ 1–3 ] Fabricating hematite nanostructures provides an effective way to enhance the PEC performance of hematite photoanodes since they can enhance charge separation, surface area, and light absorption. [ 4–6 ] High-temperature activation (HTA) is a common method to eliminate the poor lattice mismatching between hematite and fl uorine-doped tin oxide (FTO) substrate.
[ 7–9 ] However, such hematite nanostructures often suffer from severe morphology evolution under HTA, resulting in
the loss of fi ne structures that are critical for high-performance PEC. [ 7,10,11 ]
