摘要

In this letter, TiO2 coated ITO mesoporous film was prepared by dipping doctor-blade ITO mesoporous film in TiO2 Sol, followed by sintering at 500 degrees C for 30 min. The CdS quantum dots (QDs) were deposited on TiO2 coated ITO mesoporous film using sequential chemical bath deposition (S-CBD) method to form a three-dimensional (3D) electrode. The photo-activity of ITO mesoporous film/TiO2/CdS electrode was investigated by forming a photoelectrochemical cell, which indicated that the ITO mesoporous film/TiO2/CdS electrode was efficient in photoelectrochemical cell as a working electrode. The 3D electrode showed lower performance than the conventional electrode of TiO2 mesoporous film/CdS, and more works are needed to improve the performance of 3D electrode.
