Synthesis and Photocatalytic Activity of ZnxCd1–xS/TiO2 Heterostructures Nanofibre Prepared by Combining Electrospinning and Hydrothermal Method
Abstract
The ZnxCd1–xS/TiO2 hierarchical heterostructures were successfully fabricated by combining electrospinning technology and hydrothermal methods. The morphology, crystallinity, composition and band gap of ZnxCd1–xS/TiO2 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 ZnxCd1–xS/TiO2 varied from 2.33 to 2.66 eV with the change of sulphur concentration.Whenthe molar ratio of S/Ti was 0.96, the ZnxCd1–xS/TiO2 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.
