在目前的工作中，我们报告了由高度排列的纳米通道形态组成的 TiO(2) 层的自组织生长。我们表明，可以调整热甘油/K(2)HPO(4) 电解质中Ti 的电化学阳极氧化过程，以产生这些自组织TiO(2) 结构。通道直径和长度可由阳极氧化参数控制。例如，这种定向结构可以应用于染料敏化太阳能电池。
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.
