以Ti（SO4）2为钛源,采用尿素辅助水热法合成了介孔TiO2微球,利用XRD、FESEM和比表面积分析仪对样品的晶型、形貌和比表面积进行分析,探讨了尿素加入量对TiO2微球的颗粒尺寸、比表面积、孔径和孔容的影响。采用刮涂法,用所合成的介孔TiO2微球制备了染料敏化太阳能电池（DSSC）的光阳极,结果表明,尿素用量为1.2g合成的介孔TiO2微球所组装的电池在模拟太阳光的照射下（100mW/cm2,AM1.5）,光电转换效率为6.2%,明显高于商用P25纳晶所组装的电池光电转换效率（4.24%）。

Mesoporous TiOe microspheres with high surface areas were prepared by hydrothermal method using titanium sulfate as raw materials in the presence of urea, and were characterized by XRD, FESEM and surface area analyzer. The effect of the added amount of urea on the particle size, surface area and pore size of the me- soporous TiO2 microspheres were investigated. The as-synthesized mesoporous TiO2 microspheres were then used to prepare the TiO2 photoelectrode of the dye-sensitized solar cells （DSSCs） by a doctor-blade method. The results indicated that the cell assembled with the TiO2 photoelectrodes fabricated with the mesoporous Ti（）2 microspheres synthesized with 1.2g urea showed the light-to-electric energy conversion efficiency of 6.2 under illumination of simulated AM 1.5G solar light （100 mW/cm2）, which was much higher compared with a commercial Degussa P25 TiO2 nanocrystals photoelectrode （4.24%）.
