Abstract :
In this paper, graphene oxide is applied as a substrate for the synthesis of the magnetic graphene oxide-zinc oxide nanocomposite. The prepared nanocomposite (GO–ZnO–Fe3O4) are characterized using Field emission scanning electron microscopy(FESEM) and vibrating sample magnetometer(VSM). The photocatalytic performance of the synthesized samples is evaluated according to the photodegradation of methylene blue and methyl orang as organic dyes pollutant. The results of studies on the removal of dye pollution with a UV-Vis spectrometer showed that the removal of methylene blue dye is done completely in a short time and in the presence of sunlight. One of the advantages of the above nanocomposite is its very cheap, convenient and cost-effective synthesis.
