我们证明了在TiO2纳米管的合成过程中使用聚乙烯基吡咯烷酮（PVP）和乙酸可以合成具有主要暴露和化学活性（001）面的单晶状锐钛矿TiO2。在由二氧化钛单晶状锐钛矿（001）组成的光阳极中，染料敏化太阳能电池的整体转换效率得到了提高。
We demonstrate that the use of poly(vinyl pyrrolidone) (PVP) and acetic acid during the synthesis of TiO2 nanotubes may result in the synthesis of single-crystal-like anatase TiO2 with a mainly exposed and chemically active (001) facet. An enhancement in the overall conversion efficiency of dye-sensitized solar cells was observed in a photoanode consisting of TiO2 single-crystal-like anatase exposed (001) facets.
