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-H-2, N-2 adsorption-desorption and acid-base measurements and their catalytic activities for combustion of C-3-C-4 alkanes and ethanol were determined. LSCF materials show good catalytic performances: 100% conversion of C-3-C-4 and ethanol can be reached below 400 and 260 degrees 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. (C) 2010 Elsevier B.V. All rights reserved.
