Jingyuan Liu and Dalei Song 1 : 8 5 : 3 In this study, we have developed a facile route for the fabrication of a manganese dioxide–iron oxide– 0 6 reduced graphite oxide magnetic nanocomposite (MnO –Fe O –rGO). The as-obtained nanomaterial 1 2 3 4 0 2 / (MnO –Fe O –rGO) was characterized using transmission electron microscopy, Fourier-transform infrared 2 3 4 1 1 / spectroscopy, X-ray diffraction, vibrating sample magnetometry, and Brunauer–Emmett–Teller surface 7 0 n area measurements. The MnO –Fe O –rGO composite shows extraordinary adsorption capacity and fast
