  A novel method for the preparation of heterostructure nanocomposites of Magnetic Silicon Quantum Dots (Fe3O4/ SiQDs) has been reported.This method is simple, inexpensive, green, and efficient compared with the former routes utilized to synthesize the similar nanostructures.Hereby, synthesis of magnetic nanoparticles-semiconductor nanocomposites is interesting,as these nanostructures may be served as effective recoverable photocatalysts in various photodegradation reactions.Fe3O4/ SiQDs nanocomposites exhibited fluorescence, displayed excellent magnetic properties at room temperature, and have high photocatalytic melaminedegradation ability.Due to their easy recovery by magnetic separation, photocatalytic activity only decreased slightly after 15 cycles of usage.
