This article reported the electrochemical behaviors of a novel hollow carbon microspheres/manganese dioxide nanosheets (micro-HC/nano-MnO2) composite prepared by an in situ self-limiting deposition method under hydrothermal condition. The results of scanning electron microscopy reveal that MnO2 nanosheets homogeneously grow onto the surface of micro-HC to form a loose-packed microstructure. The quantity...
A hierarchical porous carbon membrane was designed and prepared through a method combining liquid-liquid phase separation and then pyrolysis process using polyacrylonitrile (PAN) as precursor. The results of scan electron microscopy, transmission electron microscope and Brunauer-Emmett-Teller characterization reveal that the 3D nanoscaled architecture with hierarchical porous structure was achieved,...
