Aiming at improving the photocatalytic properties of TiO 2 , CdS/TiO 2 binary heterojunctions with different molar ratios of CdS (0.4%, 0.5%, 0.6%) were prepared by facile fabrication of CdS on metal-organic frameworks (MOFs)-derived TiO 2 . The composition and morphology of the as-synthesized specimens were well confirmed via XRD and SEM. The photocatalytic experiments showed that the photodegradation efficiency of binary heteroconjunctions for RhB aqueous solution was higher than that of bare CdS and TiO 2 under visible light irradiation. Among of all the binary heterojunctions, the CdS/TiO 2 -0.5:1 possessed the optimal photocatalytic property (91.4%) within 70 min, which was almost 90 and 2 times as high as these of pristine TiO 2 and CdS, separately. Therefore, the rational design and construction of CdS/TiO 2 heterojunction could be adopted as a potential method to improve the visible-light photodegradation efficiency of TiO 2 .
