Synthesis of nanocrystalline SnO2 powder at 100°C

[摘要] A simple gel to crystal conversion route has been followed for the preparation of nanocrystalline SnO2 at 80–100°C under refluxing conditions. Freshly prepared stannic hydroxide gel is allowed to crystallize under refluxing and stirring conditions for 4–6 h. Formation of nano crystallites of SnO2 is confirmed by X-ray diffraction (XRD) study. Transmission electron microscopic (TEM) investigations revealed that the average particle size is 30 nm for these powders.
