Synthèse des composites d’oxyde de fer. Application catalytique

Abstract

The study presented in this thesis concerns the preparation of Fe3O4-MCM-41@ZnO nanocomposites by green chemical process. First, we synthesized Fe3O4 nanoparticles in the presence of MCM-41 in a distilled aqueous solution. In the second part, the nanocomposites prepared in the presence of ZnO is made from green plant extract (henna) in the third part. The compound that has been made is used to treat the solution of methylene blue (BM) Aqueous to remove the dye from the water as a result of a photo catalytic reaction under the influence of temperature.
