Research Abstract

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.
