| 摘 要： | 本制备方法以二氧化硒(SeO2)为硒源,以氯化亚锡(SnCl2·2H2O)为锡源,以水合肼(N2H4·H2O)为还原剂在180 ℃ 的条件下利用水热法合成了硒化锡纳米盘.产物分别用扫描电子显微镜(SEM)、X射线衍射仪(XRD)表征手段进行了表征,探索了硒化锡纳米盘的形成机理.通过一系列反应物中不同硒元素与锡元素的摩尔比的条件实验,讨论了其对反应所得产物的影响;另外,通过不同反应温度的条件实验,研究了反应体系温度对所得反应产物的影响,讨论了相关的规律.

| 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. |
