Due to their distinct catalytic capabilities, transition metal sulphides, in particular ZnS, have recently attracted a lot of interest. For a variety of uses, including photocatalysts, photodetectors, gas sensors, piezoelectric sensors, and ultraviolet lasers, ZnS is a promising material. These investigations have shown that ZnS nanocrystals are effective photo catalysts because of the quick production of electron-hole pairs by photo-excitation. It has been shown that a phase transition from cubic to wurtzite occurs when surfactant is added to the synthesis of ZnS. The hydrothermal method used in this work to create ZnS uses ethylene diamine as a surfactant. The produced sample's photophysical characteristics were assessed using X-ray diffractions (XRD), XPS, and UV/VIS spectra. The photoactivity of generated ZnS with surfactant was assessed using photocatalytic degradation of industrial waste under UV irradiation. Under the same circumstances, ZnS's photocatalytic activity was likewise examined without a surfactant. ZnS with surfactant has more catalytic activity than ZnS without surfactant.
