Controllable Synthesis of MoS2@TiO2 Composite Nanostructure by Anodic Oxidation-Hydrothermal Technique
MoS2@TiO2 composite nanostructure arrays consisting of thin MoS2 nanosheets on the surface of anodized TiO2 nanotube arrays were successfully synthesized with a facile anodic oxidation-hydrothermal technique. In this study, x-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive spectrometer and ultraviolet–visible spectroscopy (UV–Vis) were used to characterize the samples. On this basis, the photocatalytic property of MoS2@TiO2 composite nanostructure in the degradation of methylene blue was investigated. XRD results indicate that MoS2 nanosheets on the surface of anodized TiO2 nanotube arrays were in a hexagonal phase. FESEM shows that MoS2 nanosheets have a uniform distribution and low agglomeration because of the regular lamellar structure with tight arrangement. Meanwhile, the MoS2@TiO2 composite nanostructure shows the high light absorption intensity both in the ultraviolet and visible region. And the photodegradation efficiency for methylene blue is 92.10%, thus, it has potential applications in the field of photocatalysis.
