Hierarchical hybrid films of MnO2 nanoparticles/multi-walled fullerene nanotubes–graphene (MNPs/MWFNTs–GS) have been prepared via a simple wet-chemical method. For this purpose, MWFNTs (~300nm in length) are fabricated from tailoring multi-walled carbon nanotubes (MWCNTs), and then inserted into GS to pile up into a hierarchical hybrid film with the in situ formative MNPs. Scanning electron microscope,...
The cross-linked MnO2 nanowire (MNWS) network bridged with small-sized graphene (SSGS) with a uniform size of ~200 nm is prepared by a one-pot green hydrothermal route from graphene oxide sol and KMnO4. The route causes KMnO4 to react and form MnOx through both self-decomposition and etching graphene, as a result that MnOx grow into nanowires and micrometer-scale graphene is cut into SSGS simultaneously...
