摘要: Abstract SnS nanoparticles have been successfully synthesized by the ionic liquid-assisted sonochemical method (ILASM). The starting reagents were anhydrous SnCl 2 , thioacetamide, dissolved in ethanol and liquid (IL)1-butyl-3-methylimidazolium tetrafluoroborate (BMImBF 4 ) mixtures. Our experiments showed that IL plays an important role morphology of SnS. A 1:1 ethanol:IL mixture was found to yield more interesting features. lower concentration Sn (II) solution favored presence nanoplatelets. An increase ultrasonic time crystalline degree size as well. Also, effect additives 3-mercaptopropionic acid, diethanolamine, ethylene glycol, trioctyl phosphine oxide is reported. X-ray diffraction (XRD) ultraviolet–visible diffuse reflectance spectroscopy (UV–Vis-DRS) used characterize obtained products.
