Porous solids possessing large specific surfaces and easily accessible cavities have found wide applications in heterogeneous catalysis, sorption, gas sensing, optoelectronics, and design of novel nanomaterials[1].As one of the important parts of the Dye sensitized solar cell (DSSC), TiO2 photoelectrodes have the low cost and good chemical stability, which aroused great attention.In this work, mesoporous TiO2 photoanodes were prepared by sol-gel method combined with spin coating.
