摘要：

The cocatalysts of various copper morphology modified TiO2 nanotube arrays (TNTs) were prepared by electrochemical deposition. The morphologies of the samples were investigated by SEM. The reductive and oxidative copper modification strongly reinforce TNTs photocurrent response in UV and visible light region, especially the later one shows higher catalytical activity in visible light from 610nm to 740nm. The reductive copper morphology consists of Cu and Cu2O, and oxidative one comprises Cu, Cu2O and CuO by photocurrent analysis. The flat band potentials calculated by Mott-Schottky curves move positive potential direction with the oxidation depth.
