Microwave-assisted Synthesis of MgFe2O4-ZnO Nanocomposite and Its Photo-catalyst Investigation in Methyl Orange Degradation

In  this work firstly mgfe2o4 nanoparticles were synthesized via a microwave-assisted method. the product was calcinated at 900  ºc for 2h. at  the second step zinc oxide shell was synthesized on  the ferrite  under  ultrasonic  waves.  properties  of  the  product  were examined  by  x-ray  diffraction  pattern  (xrd),  scanning  electron microscope  (sem)  and  fourier  transform  infrared  (ft-ir) spectroscopy.  vibrating  sample  magnetometer  (vsm)  shows nanoparticles  exhibit  ferromagnetic  behavior.  the  photo-catalytic behavior of mgfe2o4-zno nanocomposite was evaluated using the degradation  of  organic  dyes  aqueous  solution  under  ultraviolet (uv)  light  irradiation.  the  results  show  that  mgfe2o4-zno nanocomposites  have  applicable  magnetic  and  photo-catalytic performance.
