| ABSTRACT |
|
The quantum efficiency vs. wavelength curves with different reducing treatments for the 99.99% and 98.5% $TiO_2$ ceramic electrodes have been analyzed according to the Schottky barrier model of the semiconductor-elect-rolyte interface, The model allows the main physical parameters governing the photoelectrochemical properties of the semicon-ductor to be determined. According to these data the impurity ions as three valence state ($Fe^{3+})$ in the $TiO_2$ raw materials have great influence on the photoresponse and the $TiO_2$ ceramic electrodes show much lower quantum efficiency than the $TiO_2$ single crystal due to existence of the recombination centers. |
