Abstract

The ZnCdS/TiO hierarchical heterostructures were successfully fabricated by combining electrospinning technology and hydrothermal methods. The morphology, crystallinity, composition and band gap of ZnCdS/TiO were characterized by SEM, XRD, EDS, and UV-vis diffuse reflectance spectroscopy. The results indicated the sulphur concentration had a significant influence on the composition and morphology of the products. The values of the band gap energy for ZnCdS/TiO varied from 2.33 to 2.66 eV with the change of sulphur concentration. When the molar ratio of S/Ti was 0.96, the ZnCdS/TiO hierarchical heterostructures exhibited enhanced visible light photocatalytic behaviour for the decomposition of Rhodamine B (RhB) under visible light irradiation. The photocatalytic degradation of RhB followed first-order reaction kinetics.
