Nanostructured titanium dioxide is one of the classic materials for photoelectrochemical water splitting. In the present work we dope TiO(2) nanotube anodes. For this, various low concentration bulk-Nb-doped TiO(2) nanotube layers were grown by self-organizing anodization of Ti-Nb alloys. At Nb-contents around 0.1 at%, and after an adequate heat-treatment, a strongly increased and stable photoelectrochemical water-splitting rate is obtained.
纳米结构二氧化钛是光电化学水分解的经典材料之一。在本工作中，我们掺杂 TiO(2) 纳米管阳极。为此，通过 Ti-Nb 合金的自组织阳极氧化生长了各种低浓度体相 Nb 掺杂 TiO(2) 纳米管层。在 Nb 含量约为 0.1 原子%，并经过适当的热处理后，获得了显著提高且稳定的光电化学水分解速率。
