Magnetic nanohybrid imine-palladium complex based on graphitic carbon nitride (Pd-Im@Fe3O4@g-C3N4), (Im=1,10-phenanthroline-2,9-dicarbaldehyde), as a highly active and stable photocatalyst is fabricated via a facile approach, and is developed for the degradation of Methyl orange under visible light. The catalyst was identified by techniques XRD, FT-IR, TEM, SEM, DRS and VSM. According to the results of TEM analysis, the average size of palladium/iron oxide nanoparticles is 90-100 nm. The results indicate that the photocatalytic activity of the mentioned nanohybrid in the optical degradation of methyl orange is higher compared to g-C3N4 and palladium magnetic complex.The influence of reaction parameters such as time, the dependence of degradation on the presence of the catalyst and light irradiation, pH, and also the reusability of the photocatalyst on the degradation yield have been investigated. The results showed that the degradation efficiency of methyl orange with a concentration of 20 ppm and 0.006 M H2O2 at pH = 4 and a temperature of 40 °C under visible light irradiation after 20 minutes by the catalyst is 91%.
