Nanostructured photoelectrode plays a pivotal role over photoelectrochemical (PEC) water splitting. Herein, we prepared shape-controlled semiconductor chalcogenide through a template approach. X-ray diffraction and scanning electron microscopy were used to examine the nanostructure phase purity and microstructure evolution. Semiconductor optical properties such as bandgap, band potential were analyzed with Ultraviolet-Visible diffuse reflectance spectroscopy and Mott-Schottky techniques. Thereafter, the semiconductor nanostructure was deposited on fluorine-doped tin oxide using the electrophoretic technique. Obtained photoelectrode PEC water splitting performance was analyzed with a light-emitting diode as the light source. The PEC water splitting results were discussed in detail. This work provide opportunity for control synthesis of semiconductor chalcogenide nanostructure for the efficient PEC photoelectrode. |
