TiO₂ nanotube array was prepared by anodic oxidation method on the titanium substrate, and Fe₂O₃ nanoparticles was successfully deposited on TiO₂ nanotube array by a chemical bath method. Scanning electron microscopy (SEM), X-ray diffraction (XRD) and UV-Vis diffuse reflectance spectroscopy was applied to characterize their properties and the photoelectrochemical properties and the performance of photocatalytic degradation of methylene blue was investigated. The results indicated that the Fe₂O₃ modification not only broadened the absorption spectrum of TiO₂ nanotube arrays to the visible light region, but also increased the photocurrent. The photocurrent response of Fe₂O₃ modified TiO₂ nanotube arrays was 9 times higher than undecorated TiO₂ nanotube arrays. In the photocatalytic reaction, the highest methylene blue degradation rate can reach 80%, which was 30% higher than the bare TiO₂ nanotube arrays.
