摘要
All at C? Graphenes prepared by the top-down exfoliation of graphite are shown to contain metallic impurities (see scheme, metal impurities shown as black dots). These impurities may dominate their properties and can have a negative influence on their potential applications. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
