Trade-off between Zr passivation and Sn doping on hematite nanorod photoanodes for efficient solar water oxidation: Effects of ZrO2 underlayer and FTO deformation |
| 초록 |
Herein we report the influence of a ZrO2 underlayer on the PEC behavior of hematite nanorod photoanodes for efficient solar water splitting. Akaganite (β-FeOOH) nanorods were grown on FTO substrates treated with a ZrO2 underlayer. Sintering at 800°C transformed akaganite to the hematite (α-Fe2O3) phase and induced Sn diffusion into the crystal structure of hematite nanorods from the FTO substrate and surface migration of Zr atoms from the ZrO2 underlayer toward the top layer. A cathodic shift in the onset potential as well as photocurrent enhancement was achieved by surface passivation from the ZrO2 underlayer and Sn doping from the FTO substrate to the crystal lattice of hematite nanorods. |
