In the present work, we report on the self-organized growth of TiO(2) layers consisting of a highly aligned nanochannel morphology. We show that an electrochemical anodization process of Ti in a hot glycerol/K(2)HPO(4) electrolyte can be adjusted to yield these self-organized TiO(2) structures. The channel diameter and length are controllable by the anodization parameters. This directional structure can, for example, find application in dye-sensitized solar cells.
在本工作中，我们报告了由高度取向的纳米通道形态组成的 TiO(2) 层的自组织生长。我们表明，在热甘油/K(2)HPO(4)电解质中对 Ti 进行电化学阳极氧化处理可以调整为生成这些自组织 TiO(2)结构。通道直径和长度可以通过阳极氧化参数来控制。这种定向结构例如可以在染料敏化太阳能电池中找到应用。
