| Tin Oxide Nanoparticles with Controlled Morphology and Particle Size by Hydrothermal Method | |
| 摘要: 利用氯化锡和氨水作为反应试剂，通过水热合成技术制备了近球形，棒状，椭球形，六角形等粉体形貌和粒径范围从4 nm至120 nm的纳米氧化锡粉体，并对水热合成条件对粉体的粒径和形貌的影响进行了研究。所制备的粉体的XRD分析结果显示，合成温度在160 ℃以上并且合成时间在3 h以上，粉体全部具有氧化锡晶体结构。利用透射电镜对粉体的粒径和形貌观察发现，二氧化锡粉体的形貌和粒径可通过改变溶液的浓度，合成温度与合成时间进行有效的控制，其中合成温度与溶液浓度不仅可以控制合成粉体的粒径，而且可以控制粉体的形貌。 | |

| Abstract: Tin oxide nanoparticles with different particle sizes and morphologies were synthesised by varying the concentration, heating temperature and duration time by hydrothermal method. The particles were characterised by X-ray diffraction(XRD) and transmission electron microscopy(TEM). The TEM micrographs show that spherical, rod-like, oval and Hexagonal shaped nanoparticles with particle sizes from 4 nm to 120 nm are synthesised when the parameters of synthesis are changed. XRD patterns indicate that all of nanoparticles synthesised are with the structure of tin oxide. | |
