MnFe2O4/reduced graphene oxide nanocomposite (MnFe2O4/rGO) was synthesized by a facile and green strategy, which involves in situ reduction of GO in presence of Fe2+ as well as co-precipitation of Fe3+ and Mn2+ onto the surface of rGO. The composite consists of MnFe2O4 with its primary particles (~10nm) decorated by rGO sheets, which could prevent the aggregation of the particles and ensure a relatively...
TiO2/carbon hollow spheres (TiO2/C-HSs) have been successfully prepared using a template method. During the synthesis procedures, SiO2 spheres were used as template, titanium tert-butoxide and dopamine were used as TiO2 and carbon precursor, respectively. The TiO2/C-HSs were characterized by X-ray diffraction (XRD), nitrogen adsorption-desorption measurements, scanning electron microscopy (SEM), transmission...
