Préparation, caractérisation et activité photocatalytique des nanoparticules LaFeO3.
Résumé
The aim of this work is the synthesis by sol-gel and characterization by different methods: XRD, FTIR, TGA, PSD and UV-vis of a perovskite oxide LaFeO3 .the effect of various parameterson the photodegradation of the methylene blue was studied: Photocatalyst concentration, light energy of the lamp used, the time and the crystallinity of the oxide LaFeO3.LaFeO3calcined at 800°C wich has a gain size nanometric scale of 250 nm, has the best photocatalytic activity.
