Abstract :
The photocatalysis of phenol was studied using Fe3O4/ZnO core/shell magnetic nanoparticles (MNPs). The
photocatalysts were synthesized by coating of ZnO onto the magnetite by precipitation method and characterized
by XRD, SEM and FTIR measurements. Using the Taguchi method, this study analyzes the effect of parameters such
as calcinations time, calcinations temperature and molar ratio of Fe3O4:ZnO on the photo activity of Fe3O4/ZnO
MNPs. XRD and FTIR analysis confirm that coating process was done successfully. SEM images show that the
average particle size of synthesized Fe3O4/ZnO nanoparticles was about 50 nm. The phenol removal efficiency of
88% can be achieved by using a photocatalyst which is synthesized through the optimum conditions: calcinations
temperature of 550°C, calcinations time of 2 hours and molar ratio of 1:10 for Fe3O4:ZnO.
