چکیده

The present article aimed at synthesizing ZnFe2O4 nanoparticles by thermal treatment method. After ZnFe2O4 nanoparticles had been synthesized, SiO2 shell and SiO2eAg nanoparticles were placed on them. At the next step, ZnFe2O4/SiO2 and ZnFe2O4/SiO2eAg nanocomposites were characterized by structural and morphological features. Optical properties of ZnFe2O4/SiO2 and ZnFe2O4/SiO2eAg nanocomposites were also investigated by derivation of absorption spectrum fitting and Tauc’s methods. Furthermore, the impact of SiO2 shell and Sio2-Ag nanoparticles on magnetic features of ZnFe2O4 nanoparticles was evaluated. The roles of reactive oxygen species (ROS) on degradation of MB dye solution in the presence and absence of H2O2 was also analyzed.
