Abstract: SnSe2 nanodisks were synthesized in a hydrothermal system at 180 ℃ using SeO2 as selenium source, SnCl2·2H2O as tin source, N2H4·H2O as reductant.A series of analytic instruments, such as X-ray powder diffraction (XRD) and scanning electron microscope (SEM) , were used to reveal the characterization of SnSe2 nanodisks.The formation mechanism of SnSe2 nanodisks was researched, and the influence of mole ratio and reaction temperature was discussed.
