SnSe2 nanosheets with the thickness of 30–50 nm have been synthesized by solvothermal method using ethylene glycol solution as solvent. The influence of synthetic parameter, such as reaction time, on the morphologies of SnSe2 has been investigated. The morphologies and the crystal structures of SnSe2 nanosheets were characterized by X‐ray powder diffraction (XRD), field‐emission scanning electron microscopy (FE‐SEM).
