Abstrakt: The CdS quantum dots sensitized TiO2 nanotubes were prepared by sequential chemical bath deposition (S-CBD) method and characterized by FE-SEM and UV-vis spectroscopy. And they were used to degrade the dimethyl phthalate (DMP) in aqueous under sunlight irradiation. The results show that these photo-catalysts have the highest performance, while the initial concentration of dimethyl phthalate in aqueous solution is 10 mg / L, the degradation rates reaches above 80% in the optimum condition which is the CdS deposited 20 cycles, catalyst dosage ~3cm2, and the sunlight irradiating 180 minutes.
