In this study, we developed a novel process for the synthesis of anatase-type TiO_2 nanocrystals with specific crystal plane on the crystal surface using layered titanate nanosheets as the precursor and studied their photocatalytic activity and dye-sensitized solar cell performance. The TiO_2 nanocrystals with (010) plane on the surface can be prepared by hydrothermal treatment of H_<1.07>Ti_<1.74>O_4 nanosheet solution. The (010) plane presents the high photocatalytic activity and high dye adsorption amount. The results of dye-sensitized solar cell study indicate that the V_<oc> value increases with increasing the dye adsorption amount and the J_<sc> value increases with increasing adsorption constant. We give the quantitative relationships between the dye adsorption parameters and solar cell parameters for the first time.

本研究以层状钛酸盐纳米片为前驱体，开发了一种具有特定晶面的锐钛矿型TiO_2纳米晶体的合成方法，并对其光催化活性和染料敏化太阳能电池性能进行了研究。采用H_<1.07>Ti_<1.74>O_4纳米片溶液水热处理，可以制备表面具有（010）平面的TiO_2纳米晶。（010）平面具有较高的光催化活性和较高的染料吸附量。染料敏化太阳能电池的研究结果表明，V_<oc>值随染料吸附量的增加而增加，J_<sc>值随吸附常数的增加而增加。首次给出了染料吸附参数与太阳能电池参数之间的定量关系。
