A Facile Method For Synthesis Of Sns2 With Different Morphologies By An Ambient Pressure Tetraethylene Glycol Solution Process

An ambient pressure solution chemical process was used for synthesis of SnS2 nanocrystals with different morphologies such as nanoparticles, nanosheets, nanospheres and so on. The process was conducted by using diethylene glycol as solvent, stannic chloride and thioacetamide as precursors, polyvinylpyrrolidone as capping agent. The influence of synthesized temperature and reducing agent on the morphologies and phases of product were investigated based on XRD, TEM, HRTEM and EDX. Optical properties of SnS2 nanocrystals were characterized. The results showed that pure phase, ultrathin SnS2 nanosheets were prepared with few polyvinylpyrrolidone exited.
