Abstract
The nanoporous titania powders are prepared under hydrothermal conditions using the amphiphilic triblock copolymer (Pluronic P123) as the porogent, and characterized by means of XRD and BET. Then, nanoporous TiO2 electrodes are fabricated by Doctor-blade mehod, using the nanoporous TiO2 powders as anode materials, and the photoelectronic properties of the DSCs are investigated by measuring transient photocurrent spectrum and photocurrent action spectra. The results indicate that the porous titania powder have pure anatase structure, and the specific surface area is up to 68m2g-1. In addition, the nanoporous TiO2 electrode shows higher photoelectric performance compared with pure TiO2 electrode.
