| Mesoporous Titanium dioxide is a kind of important semiconductor material. It has been widely used in domain of photoelectricity, gas sensitized and photocatalytic. In order to utilize this kind of capability and to gain more large surface area to the application in Dye-sensitized solar cells, it is necessary to synthesize the mesoporous TiO2. With simple chemical method, mesoporous TiO2 were prepared and Dye-sensitized solar cells were made in this paper. Various analytic methods such as XRD,TG-DSC,BET,HRTEM and ESEM etc, were used to character the prepared powders and the volume of Surfactant were employed to study the affected of the diamater of mesoporous TiO2.By sol-gel method,the mesoporous TiO2 were synthesized. The diamater of the synthesized mesoporous TiO2 is raged from five nanometers to 10 nanometers, the paper discussed how the volume of Surfactant affects the synthesized mesoporous TiO2. By the hydrothermal synthesis of mesoporous TiO2,changing the volume of Surfactant, discussed how the volume of Surfactant affects the synthesized mesoporous TiO2.The result:The diamater of the synthesized mesoporous TiO2 is raged from ten nanometers to forty nanometers by the surfactant of CTAB; the diamater of the synthesized mesoporous TiO2 is raged from five nanometers to forty thirty-five nanometers by the surfactant of P123; by the surfactant of both of CTAB and P123, the diamater of the synthesized mesoporous TiO2 is raged from six nanometers to thirty-five nanometers.As to the single use of CTAB or P123, the use of both of CTAB and P123 make the size of mesoporous TiO2 more uniformity, and the raged diamater of mesoporous TiO2 are wider. The larger surface area and bigger diamater were acquired. By joint use of CTAB and P123, the synthesized mesoporous TiO2 were used in Dye-sensitized solar cells. The result shows that the the best average value of the diamater is 38 nm, and the larger the surface area, the higher efficiency of the cells. |
