Characteristics of $TiO_2$ Ceramic Electrode for the Photoelectrochemical Conversion

광전기 화학 변환을 위한 $TiO_2$ 세라믹 전극의 특성

  • Published : 1983.04.01

Abstract

The photocurrent vs. potential characteristics of the $TiO_2$ ceramic electrodes have been investigated as functions of numerous variables including sample purity hydrogen reduction condition and pH of the electrolyte. The difference inphotoresponse between 99.99% and 98.5% $TiO_2$ electrodes was due to electron trapping effect. As the hydrogen reducing temperature of $TiO_2$ electrodes were increased the photocurrent was also increased to certain condition and then decreased. These results can be explained by the behavior of oxygen vacancies.
