摘要：

Activated carbon (AC) supported Fe3O4 nanoparticle-based composites (CFFs) have been prepared by mixing AC with a Fe3O4 ferrofluid followed by drying. These composites display a unique combination of electrical and magnetic properties along with nanoporosity. The structural, morphological and magnetic properties of the synthesized CFF composites have been characterized by XRD, SEM, TEM, VSM and TGA. The water purification capability has been demonstrated using methyl orange (MO) dye as an impurity. The porosity and magnetic properties enable fast adsorption of MO and magnetic separation of MO adsorbed OFF particles, respectively. In addition to water purification, these multifunctional CFFs may also find promising applications in catalyst separation, bioreactors, and for shielding electromagnetic interference in the microwave frequency range.
