A unique CdS/Fe3O4/rGO composite photocatalyst is successfully synthesized by the microwave method. It displays promising photocatalytic activity towards the photo-degrading of tetracycline (TC) in aqueous solution, the degradation rate of TC is 69% with adding 0.1[Formula: see text]g CdS/Fe3O4/rGO photocatalyst into 20[Formula: see text]mg/L tetracycline for 2[Formula: see text]h under visible light irradiation. Furthermore, the mechanism was systematically investigated by active species trapping experiment. It can be known that [Formula: see text] the major active species in the photodegradation process and the possible process of charge transfer for CdS/Fe3O4/rGO was proposed based on the experimental results. The as-prepared samples were carefully evaluated by XRD, TEM, XPS, VSM, PL spectra, Raman spectrometer.
