Perovskite Type Oxides: A Novel Type of Catalysts Suitable for Hydrogen Peroxide Decomposition

Published

Conference Paper

La 1-x Sr x MnO 3 (0 ≤ x ≤ 0.8) Perovskite-type oxide powders were synthesized by sol-gel method and their catalytic activity for the H 2 O 2 decomposition was investigated. H 2 O 2 decomposition was observed as first-order reaction on these catalysts. With the increase of Sr substitution, the catalytic activity increased accordingly. The compensation effect was found for these perovskites. Through analysis of the kinetic results, Mn 4+ ions were attributed to the active sites of H 2 O 2 decomposition. Al 2 O 2 supported La 1-x Sr x MnO 3 were prepared and showed good performances in monopropellant thruster tests.
