Recently, transition metal sulphides, in particular ZnS have been intensively studied because of its unique Catalytic functions. These studies have revealed that ZnSnanocrystal are good photo catalysts due to rapid generation of electron–hole pair by photo-excitation. By adding surfactant in synthesis of ZnS, it has been observed that there is phase transition occurs from cubic to wurtzite. In the present work, ZnS is prepared by hydrothermal process using Ethylene diamine as surfactant. Prepared sample were characterized by X-ray diffractions (XRD), FTIR, UV/VIS spectra were recorded for evaluation of photo physical properties. The photo activity of prepared ZnS with surfactant was accessed by photo catalytic decomposition of industrial waste under UV irradiation. Under the same condition photocatalytic activity of ZnS without surfactant was also examined. The ZnS with surfactant shows higher catalytic activity compare to ZnS without surfactant. |
