In this study, magnetite Fe3O4/ZrO2/nanographene platelets (NGP) and Fe3O4/ZrO/graphene composonsites were prepared successfully by depositing the Fe3O4/ZrO2 composites onto the surface of NGP and graphene using co-precipitation method as an effort to improve photo- and sonocatalytic performance. The structure and magnetic properties of the as-prepared samples were characterized by XRD and TGA. The catalytic activity of Fe3O4/ZrO2/NGP and Fe3O4/ZrO2/graphene composite towards methylene blue (MB) from the aqueous solution were investigated under UV light and ultrasound irradiation, separately. It was found that the incorporation of NGP and graphene in Fe3O4/ZrO2 could greatly improve photo- and sonocatalytic performance. The incorporation of graphene with the higher surface area than NGP exhibits the best catalytic performance. In addition, scavengers of reactive species on the degradation activity were investigated.
