Zusammenfassung:Pave a way to high‐performance anode materials: Organic metal/graphene composites are fabricated through an in situ assembly of disc‐shaped phthalocyanine molecules with graphene sheets during the chemical reduction of graphite oxide, which enables a homogenous dispersion of Co and Co3O4 nanoparticles in the sheets after simple pyrolysis and oxidation. The resulting Co3O4/graphene composites exhibit remarkable lithium storage performance.
