Abstract

Abstract In this paper, a series of CdS/TiO 2 NTs have been synthesized by SILAR method. The as-prepared CdS/TiO 2 NTs have been analyzed by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive spectrometer (EDS), and ultraviolet–visible (UV–vis). And their photocatalytic activities have been investigated on the degradation of methylene blue under simulated solar light irradiation. XRD results indicate that TiO 2 NTs were anatase phase, CdS nanoparticles were hexagonal phase. FESEM results indicate that low deposition concentration can keep the nanotubular structures. UV–vis results indicate that CdS can be used to improve the absorbing capability of TiO 2 NTs for visible light, and the content of CdS affects the band gap. Photocatalytic results indicate that CdS nanoparticles are conducive to improve the photocatalytic efficiency of TiO 2 NTs, and the highest degradation rate can reach 93.8%. And the photocatalytic mechanism of CdS/TiO 2 NTs to methylene blue is also described.
