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


Conference Paper

La1-xSrxMnO3 (0 ≤ x ≤ 0.8) Perovskite-type oxide powders were synthesized by sol-gel method and their catalytic activity for the H2O2 decomposition was investigated. H2O2 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, Mn4+ ions were attributed to the active sites of H2O2 decomposition. Al2O2 supported La1-xSr xMnO3 were prepared and showed good performances in monopropellant thruster tests.
