Abstract

CdS quantum dots (QDs) sensitized TiO₂ films were successfully synthesized using one-step microwave assisted chemical bath deposition method, which allows a facile and rapid deposition and integration between CdS QDs and TiO₂ films. The photocatalytic performance of the films fabricated using CdS precursor solutions with different concentrations in the reduction of Cr(VI) under white light emitting diode (LED) light irradiation was investigated. The results show that the CdS sensitization can enhance the photocatalytic performance of TiO₂ film with a maximum reduction rate of 93% for 240 min under white LED light irradiation as compared with the pure TiO₂ film (31%) due to the increase of light absorption and the reduction of recombination of the injected electrons from CdS to TiO ₂.
