Abstract

Various morphologies of SnO₂ were successfully synthesized using a solution process. The porous structure SnO₂ synthesized by sol-gel method using SiO₂ microparticles as a template showed excellent specific surface area and oxygen storage capacity (OSC) even after annealing at 1000 °C for 20 h. Alkali earth metal ion doped SnO₂ porous structure nanoparticles were also synthesized successfully by adding M(NO₃)₂·xH₂O (M = Mg, Ca, Sr, Ba) to the reaction solution. The alkali earth metal ion doping greatly enhanced the thermal stability and OSC of SnO₂. Especially, Sr²⁺ doped SnO₂ with porous structure annealed at 1000 °C for 20 h possessed high BET surface area and exhibited a considerably high OSC and excellent thermal stability. Alkali earth metal ion doped SnO₂ particles showed a great potential for application to a novel oxygen storage material.
