Inside Cover: Graphene Oxide Nanoribbons from the Oxidative Opening of Carbon Nanotubes Retain Electrochemically Active Metallic Impurities (Angew. Chem. Int. Ed. 33/2013)
Graphical Abstract
Metallic impurities influence the properties of graphene oxide prepared from carbon nanotubes. In their Communication on page 8685 ff., M. Pumera et al. show that the graphene oxide contains metallic impurities that survive the oxidative treatment of carbon nanotubes. Similar to metal-based impurities in sandstone, which give color to the displayed Antelope Canyon, these metallic impurities influence the properties of the resulting graphene oxide.
