Use of strontium titanate (SrTiO3) as an anode in solid oxide fuel cells has attracted considerable research attention because of its excellent thermal stability. Mesoporous SrTiO3 increases the specific surface area for fuel cell reaction, which in turn increases the fuel-to-electricity conversion efficiency. Spray pyrolysis (SP) is advantageous because it entails short processing times and continuous production. In this study, we prepared mesoporous SrTiO3 particles through SP. Because surfactants, as pore forming agents, may aggregate and reduce the specific surface area of particles, the stable surfactant concentration range was investigated. In addition, the short calcination time of SP may cause incomplete decomposition and thus generate an unreacted phase; therefore, various calcination temperatures and an additional wash treatment were explored. Finally, SrTiO3 powder with the high specific surface area of 103 m(2)/g was obtained.
