Hydrothermal Synthesis of Tin Oxide Nanoparticles
水热法合成纳米SnO2粉体

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.
