Detailed Characterization of Hydrothermally Synthesized SnO2 Nanoparticles

3-4 nm of SnO2 nanoparticles having uniform spherical shape were successfully synthesized using a hydrothermal method. The hydrothermal method has many advantages over other methods of preparing nanoparticies (such as sol-gel, solid state, and chemical precipitation), because there is no need for calcination and nailing steps. The particles were characterized by X-ray diffraction, pore size diamater analysis, transmission electron microscope, scanning electron microscope analysis, Raman spectroscopy, and thermogravimetric analysis/differential thermogravimetric analysis. The results confirm that SnO2 nano powders are homogeneous, nano scale, and of high crystalline quality.
