“…To increase the surface area of perovskite-type catalysts, many investigators have developed new methods. For example, our group prepared porous La 1−x Sr x Mn 0.8 Fe 0.2 O 3 (0≤x≤0.6) microspheres with a surface area of 55.73 m 2 •g −1 through a low temperature molten salt approach 9 . Furthermore, some researchers dispersed perovskite catalysts on high surface area supports, e.g., mesoporous SiO 2 10 , SBA-15, MCM-41 11 ,…”
