Abstract |
Fe2O3 has been extensively investigated as a promising materials for photoelectrochemcial water splitting due to its 2.2 eV of favourable band gap, chemical and physical stabilities, abundant, and low cost. However, the reported efficiencies of water splitting are relatively lower than theoretically predicted value, mainly because of the extremely short life time of photogenerated charge carriers’ and diffusion length, inert oxygen evolution reaction, and low flat band potential. In order to enhance the efficiency, various approaches are considered such as nanostructuring, doping, and co-catalysis. Particularly, for nanostructuring various approaches are used like hydrothermal, sol-gel, and electro deposition. Here, we are focused on formation of Fe2O3 nanostructures by electrodeposition on nano patterned fluorine-doped tin oxide (FTO) glasses. In order to achieve, porous FTO structures were formed by electrochemical etching before Fe2O3 deposition. Finally, we studied about the relationship between physical properties of porous FTO and photoelectrochemcial efficiency. |
