Cover Picture: A Facile Method to Prepare Three-Dimensional Fe2O3/Graphene Composites as the Electrode Materials for Supercapacitors (Chin. J. Chem. 1/2016)
The cover picture shows the structure of three-dimensional graphene/Fe2O3 composite as a promising electrode material for supercapacitor, as well as the potential application of supercapacitor in electric automobile. The composites are synthesized via a one-step reaction between graphene oxide and Fe2+ at a mild condition. During the reaction, graphene oxide sheets are reduced and self-assemble into a 3D network, while Fe2+ is converted into Fe2O3 and deposited onto the graphene network. This structure facilitates the diffusion of the electrolyte and the electron transfer between Fe2O3 and the current collector, thus endowing the composites with high capacitive performance. More details are discussed in the article by Bai et al. on page 67–72.
