摘要
本文以SnCl2.2H2O为原料、无水乙醇为溶剂、NaOH为碱源,采用水热法制备出晶粒尺寸只有数纳米的SnO2粉体。并利用XRD、TEM等分析方法对所得的SnO2粉体进行了表征,XRD衍射峰显示为四方相金红石型SnO2,随温度升高,衍射峰宽度明显变窄,晶粒变大。TEM表明粉体晶粒尺寸为数纳米,团聚很少,分散性能良好。
Tin oxide nanoparticles were synthesized by the hydrothermal method, using SnCl2·2H2O, C2H5OH and NaOH as reactants. The obtained particles were characterized by XRD and TEM. XRD patterns show that as-prepared samples are of the tetragonal rutile structure of SnO2, and the width of the diffraction peaks of SnO2 becomes narrower with increasing temperature, TEM confirms that the morphologies of SnO2 particles are nanocrystals, and that the diameters of SnO2 particles have narrow size distributions.
