Abstract

The surface charge-tunable Fe₃O₄ nanoparticles with high dispersibility and high superparamagnetism are fabricated by a facile electrochemical method in acetonitrile. These nanoparticles can reversibly bind to graphene oxides, which could be recycled and continually used for high-efficient removal of dye pollutants from water.
