Abstract :
[en] The main goal of this work is the preparation of magnetic perovskites La1-xSrxMnO3 (x= 0, 0.2 and 0.4) with a modified sol-gel process and the assessment of their catalytic activity in the oxidation of styrene in neat water (aqueous medium). The structural properties of LaMnO3, La0.8Sr0.2MnO3 and La0.6Sr0.4MnO3 were characterized using the X-ray Diffraction and infrared techniques. Microstructural features of the catalyst were confirmed by the Scanning Electron Microscopy. The sample La0.6Sr0.4MnO3 has proven a good catalytic activity in the oxidation of styrene after different optimization steps. The catalyst has shown a good recyclability after four cycles. The optimized parameters of the reaction procedure were applied successfully in the oxidation of other simple olefins.
