The nanoporous titania dispersion system are prepared under hydrothermal conditions by employing various amount β-cyclodextrin(CD) as the porogent.Then, different microsructure nanoporous TiO2 electrodes are fabricated by Doctor-blade mehod, using the above synthesis of titanium dioxide materials.The photoelectrochemical properties of dye-sensitized nanoporous TiO2 electrodes are studied with transient photocurrent spectrum ,electrochemical impedence spectra (EIS) and photocurrent action spectra. The results indicate that the current response signals of dye-sensitized porous TiO2 electrodes are stable. In addition,the impedence arc radius decreases gradually and light current increases gradually with the addition of β–CD. Meanwhile, the dye-sensitized porous electrodes with β-CD/TiO2 =40 wt% showes the best photoelectrochemical properties.
