自1972年以来，TiO 2的光催化活性引起了广泛的研究努力。虽然TiO 2在利用紫外光方面具有非常高的效率，但由于其宽带隙（约3.0-3.2 eV），其整体太阳能活性非常有限。这是TiO 2在可见光催化、光化学、光电化学、传感器等领域应用的瓶颈。近年来，黑色TiO 2纳米材料的出现引起了世界范围内的研究兴趣，因为它大大增强了太阳能的吸收和提高了光催化活性。本文综述了黑色TiO 2的各种合成方法，详细介绍了黑色TiO 2纳米材料的结构、化学特征、能带结构和电子性质，并沿着介绍了其光催化性能以及其他一些新的应用。
The photocatalytic activity of TiO2 has aroused a broad range of research effort since 1972. Although TiO2 has a very high efficiency in utilizing ultraviolet light, its overall solar activity is very limited due to its wide bandgap (approximate to 3.0-3.2 eV). This is a bottleneck for TiO2 to be applied in the areas ranging from visible-light photocatalysis and photovoltaics to photo-electrochemistry and sensors. Recently, the emergence of black TiO2 nanomaterial has triggered world-wide research interest, because of its substantially enhanced solar absorption and the improved photocatalytic activities. Here, a variety of synthetic strategies of black TiO2 are outlined, and the structural and chemical features, band structures and electronic properties of the black TiO2 nanomaterials are described in details, along with their photocatalytic performances as well as some other new applications.
