The results showed that the films is rutile TiO2, and its crystal orentation is dependent on the thermal oxidation temperature. With increasing the oxidation temperature, the photocurrent and open-circuit voltage of TiO2/TiNi electrode first increased, and then decreased. when the oxidation temperature was 700 ℃, the photocurrent of TiO2/TiNi electrode was the highest. %U http://www.yxkxyghx.org/EN/10.7517/j.issn.1674-0475.2005.03.161
