Morphology-controlling synthesis of ZnS through a hydrothermal/solvthermal method

Abstract Different morphologies of ZnS have been synthesized by a solvothermal process, through the reaction of Zn(CH 3 COO) 2 ·2H 2 O and SC(NH 2 ) 2 in different mixed solvents, changing the density of the surfactant (C 12 H 25 SO 3 Na). The samples were characterized by the X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy-dispersive X-ray analysis (EDAX) techniques. The results show that the as-prepared ZnS have different morphologies, such as lamellar ZnS, smooth microspheres, roughen microspheres, plate-like ZnS and so on. So far, to our knowledge, lamellar ZnS have not been synthesized by solvothermal route before.
