Synthesis, characterization and catalytic performance of LSCF perovskite for VOC combustion

Perovskite-type La0.6Sr0.4Co0.2Fe0.8O3 (LSCF) mixed oxides were successfully prepared by combustion and reactive grinding method, characterized by XRD, ICP, XPS, TEM, SEM, TPR-H2, N2 adsorption–desorption and acid–base measurements and their catalytic activities for combustion of C3–C4 alkanes and ethanol were determined. LSCF materials show good catalytic performances: 100% conversion of C3–C4 and ethanol can be reached below 400 and 260 °C, respectively, and activity was stable with extended time on stream and for repeated temperature cycles as well. LSCF materials seem then to be promising alternative to noble metal based catalysts for VOC oxidation.
