초록

티타늄 금속판을 양극산화하여 제조한 $TiO_2$ 박막을 전극으로 사용하여 1M NaOH 용액에서 광전기화학적 성질을 연구하였다. $TiO_2$ 전극들의 flatband potential은 대략 -0.8V 정도로 이들 값은 단결정 $TiO_2$에서 보다 0.2V만큼 양전위 방향으로 이동되어 나타났다. 순환 전압 전류법에 의한 산소의 환원전위는 SCE에 대해 -0.95V 근처에서 나타났으며, 반응은 전체적으로 비가역적으로 진행되었다. 또한 전극의 광전류는 단결정 $TiO_2$에서 보다 더 단파장에서 나타났으며 전류밀도는 감소되었다.

The titanium oxide thin films were prepared by anodic oxidation. The Photo-electrochemical properties of the electrodes were studied in 1 M NaOH solution. The flat band potentials of $TiO_2$ electrodes prepared by anodic oxidation showed around -0.8V and the values were shifted 0.2V to the positive potential direction that of single crystal $TiO_2$. Reduction potential of oxygen by cyclic voltammetry showed around -0.95V vs. SCE and these reactions were processed totally irreversible. The photocurrent of electrodes were showed shorter wavelength than that of single crystal $TiO_2$ and its current density decreased.
