Fine-tuning pulse-reverse electrodeposition for enhanced photoelectrochemical water oxidation performance of α-Fe2O3 photoanodes |
| 초록 |
High-quality hematite (α-Fe2O3) photoanodes were synthesized from a sulfate electrolyte bath by pulse-reverse electrodeposition method. The influence of parameters of pulse electrodeposition process was systematically investigated such as duty cycle, pulse period and deposition time, on the structural, optical, morphological, and photoelectrochemical properties of the films. The optimized parameters of pulse duty cycle, pulse period and the deposition time were 20%, 10 ms and 45 s, respectively. The nanocrystalline morphology of the α-Fe2O3 was found to alter according to the process parameters. The α-Fe2O3 electrodes prepared by annealing at 550oC for 4h followed by 800oC for 15 min exhibited an optimum photocurrent density of 504 µA cm-2 measured at 1.23 V vs. RHE. |
