In this research, we demonstrate the preparation of ternary Ag/Fe3O4/ZrO2 composites as a novel magnetically separable UV-light-driven photocatalyst. The Fe3O4/ZrO2 composites were successfully synthesized by using two-step methods, that is, sol-gel followed by ultrasonic-assisted method. Furthermore, the Fe3O4/ZrO2 composites were coupled with silver through ultrasound-assisted method. The prepared samples were fairly characterized by using X-Ray Diffraction and UV-Vis DRS spectroscopy. The photocatalytic activity of this composite was tested to degrade methylene blue dyes under UV-light irradiation. The influence of catalyst dosage, initial concentration, and scavengers of active species were investigated and the results were discussed. Compared with Fe3O4/ZrO2 sample, the Ag/Fe3O4/ZrO2 composite with three weight ratio (5%, 15%, and 25%) of Ag to Fe3O4/ZrO2 display higher photocatalytic activity. Among three variations of the weight ratio of Ag to Fe3O4/ZrO2, 15% weight ratio of Ag in Ag/Fe3O4/ZrO2 exhibits the superior photocatalytic performance followed by weight ratio of 25% and 5%. Moreover, the composite was found to be a reusable catalyst.
