Antimony-doped tin dioxide nanometer powders prepared by the hydrothermal method

Add time:09/03/2019    Source:sciencedirect.com

Antimony doped tin dioxide nanometer powders have been prepared by the hydrothermal method using SbCl3 as the source of antimony. The doped powders are examined by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The crystal phase composition, particle size, crystal appearance characteristics and dispersity of the doped powders are investigated. The results show that doped powders are well crystallized and dispersed. The crystal phase composition of doped powders is SnO2 of tetragonal structure. The particle size of doped powders is ∼3–12 nm. The crystal appearance characteristics of doped powders are mainly round. Antimony enters crystal lattice of tin dioxide via Sb3+. The doping effect of antimony is very good.
