摘要: 采用电化学阴极还原和阳极氧化法, 制备了还原态铈和氧化态铈改性的TiO₂纳米管阵列, 通过扫描电子显微镜(SEM)和X射线衍射(XRD)表征样品形貌和晶相, 得出还原态铈以单质铈纳米纤维形式存在于TiO₂纳米管内及表面, 单质铈改性的TiO₂纳米管经阳极氧化后, 以CeO₂和单质Ce形式共存. 测定样品的光电流响应并计算样品的能带宽度. 结果表明: 单质铈改性的TiO₂纳米管阵列在可见光区光电流响应较TiO₂纳米管增强,单质铈添加存在最佳值, 在10 mmol·L^-1溶液中制备的单质铈改性的TiO₂纳米管阵列光电流响应最强, 能带宽度E_g减少到2.88 eV, 并且随着单质铈含量的增加, 载流子浓度增大, 且平带电位向负向移动. 单质铈改性的样品经阳极氧化后, 样品在紫外光区和可见光区光电流响应都增强, 但其在可见光区的响应强度要小于单质铈改性的TiO₂纳米管在可见光区的响应强度.

Abstract: Well-ordered TiO₂ nanotube arrays were prepared by electrochemical anodization onto a pure Ti sheet in an organic solution. Reduced cerium and oxidized cerium were deposited onto the TiO₂ nanotube arrays by electrochemical cathodic reduction and then anodic oxidation. The morphology and crystalline phase were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD), which indicated that the reduced cerium was in the form of elemental cerium nanofibers and they were dispersed over the surface of the TiO₂ nanotube. The oxidized cerium was present as elemental cerium and cerium dioxide after oxidation. The photocurrent was measured and the bandgap energies were calculated. The results showed that the photocurrent response of the TiO₂ nanotube arrays modified by the reduced cerium was enhanced in the visible spectra rather than in the UV spectra. The optimum amount of deposition was found for the sample prepared using the 10 mmol·L^-1 cerium nitrate solution and with a bandgap energy of 2.88 eV. Also, the carrier density increased and the flat band potentials moved to the negative direction as the cerium content increased. After anodic oxidation, the photocurrent response of the samples increased in the visible spectra and in the UV spectra. However, the photocurrent response modified by oxidized cerium in visible spectra is weaker than that of the TiO₂ nanotube arrays modified by reduced cerium.
