以硝酸锡为原料,配成稳定溶液,进行水热反应合成得到了晶粒尺寸只有数纳米的SnO2粉体.以FT-IR,XKD,TEM等分析手段对粉体进行了表征.FT-IR表明所得粉体均已实现了晶化.XRD衍射峰显示为SnO2相,衍射峰宽化明显,且随水热温度的升高宽化变窄,结晶性提高.粉体的晶胞体积随水热温度也呈现规律性变化.TEM表明粒子均为数纳米,粉体的分散性能良好,团聚很少.
Nanocrystalline tin oxide particles were synthesized by the hydrothermal method from the starting
material tin nitrate, free from the widely used tin chlorides. The obtained nanoparticles were characterized by means of FT-IR, XRD and
TEM. FT-IR shows that the particles are well crystallized at the hydrothermal temperatures. XRD shows that the obtained particles are
in the cassiterite structure (SnO2), and the diffraction peaks are considerably broadened and the broadening becomes narrower as the hydrothermal temperature
turns higher. The unit cell volume of the SnO2 nanoparticles shrinks with the growth of the particles. TEM shows the particles are all monodispersed and have narrow size distributions.
