Facile Synthesis of Hierarchical ZnS Microspheres and their Photocatalytic Properties

Abstract:

Hexagonal ZnS nanostructured spheres self-assembled from ZnS nanocrystals were successfully synthesized through a facile hydrothermal method using 1-butyl-3-methlyimidazole thiocyanate ([BMIM][SCN]) as both sulfur source and capping ligand. By combining the results of X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), field-emission scanning electron microscopy (FE-SEM), ultraviolet–visible (UV–vis) absorption spectra, a structural and morphological characterization of the products was performed. The photocatalytic activity of ZnS microspheres had been tested by degradation of Rhodamine B (RB) under UV light compared to commercial ZnS powders, which indicated that the as-syntherized ZnS spheres exhibited enhanced photocatalytic activity for degradation of RB.
