Low temperature molten salt synthesis of porous La1-xSrxMn0.8Fe0.2O3 (0 ≤ x ≤ 0.6) microspheres with high catalytic activity for CO oxidation

A spherical porous perovskite oxide with a better morphology and higher catalytic activity for CO was synthesized by the molten salt method at 450 °C for 4 h using hierarchical porous δ-MnO2 microspheres as template.
