An improved stability and enhanced charge transport in Al2O3 coated CdS/1D Zr:Fe2O3 nanorod arrays for efficient solar hydrogen generation |
| 초록 |
CdS coated Zr:Fe2O3 nanorod arrays have been synthesized on fluorine-doped tin oxide via a two-step hydrothermal method. The photoelectrochemical results demonstrate that the current density (4.2 mA.cm-2 at 0 V (vs. Ag/AgCl) recorded under illumination for the CdS/1D Zr:Fe2O3 is 2.8 time higher than the bare Zr:Fe2O3. The reduced recombination, and the effective transport of photogenerated holes in CdS to the electrolyte facilitate enhancement in photoelectrochemical performance. XPS and TEM observation of the bare and aluminium treated CdS/1D Zr:Fe2O3 photoanodes indicated that the presence of Al2O3 on surface of CdS and Zr:Fe2O3 nanorods embedded in the CdS flakes. Furthermore, the photocurrent and stability of the CdS/Zr:Fe2O3 nanorods was significantly enhanced by Al2O3 compared to bare CdS/Zr:Fe2O3 heterojunction due to its ability to act as an effective hole transport as well as photo-corrosion protecting layer. These remarkable enhancements in improvement in charge transport and stability suggest the usefulness of photoanodes for solar hydrogen generation. |
