Abstract
- In this work, we reported the synthesis of zinc sulphide microspheres using the hydrothermal method. ZnS microspheres were synthesized using water, zinc acetate, thiourea and ammonia solution at 150°C for 6 h, 12 h, and 24 h. The as-synthesized ZnS powders were characterized by x-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and ultraviolet–visible (UV–Vis) spectroscopy. XRD indicates the cubic (major phase) as well as hexagonal (minor phase) crystalline phase with enhanced crystallinity increased gradually with more reaction time. UV–Vis spectra show the absorption peaks in the UV–Vis region for all the samples. The Tauc’s plot was used to calculate the band gap energy of ZnS samples, which are found to be 3.39 eV, 3.4 eV, and 3.42 eV for the samples synthesized at reaction times of 6 h, 12 h, and 24 h, respectively. FESEM images confirm the formation of microspheres as aggregates of spherical nanoparticles. The as-synthesized ZnS microspheres have been explored for solar light-induced photo-catalytic dye degradation of methylene blue (MB), and the results confirm that such microspheres exhibit effectual photocatalytic properties. Zinc sulphide microspheres have been synthesized hydrothermally at different reaction times (6 h, 12 h, and 24 h). The as-synthesized ZnS microspheres were successfully employed as photocatalyst for MB dye degradation. Due to high crystallinity, ZnS microspheres synthesized for 24 h show more efficient degradation potential than others.
