The electrochemical performance of a material varies with its structural phase transition. It is found that the rhombohedral Fe2O3 can transform to the cubic Fe3O4 via a calcination treatment in a nitrogen atmosphere, and lithium-ion storage performances of Fe3O4 get an obvious improvement due to its structural advantages. On the basis of data calculated by X-ray diffraction, the larger unit cell...
In this paper, we propose a novel fabrication for manganese monoxide and reduced graphene oxide nanocomposite (MnO/rGO), in which microemulsion is introduced to form a 3D architecture consisting of MnO nanoparticles embedded in reduced graphene oxide network. Physical characterizations from SEM, TEM, HRTEM, XPS, Raman, and XRD, indicate that MnO particles of about 230nm are formed and uniformly embedded...
