“…However, the practical application of graphene is limited by its large aspect ratio, which lengthens the lithium-ion transport pathway and promotes aggregation. Interestingly, graphene acts as an effective substrate. ,, The porphyrin-based macrocyclic structure of metal naphthalocyanines can provide possible covalent or noncovalent interactions with graphene oxide (GO), inhibiting the self-aggregation of naphthalocyanine molecules and graphene, thereby improving electrical conductivity …”

“…18,23, The porphyrin-based macrocyclic structure of metal naphthalocyanines can provide possible covalent or noncovalent interactions with graphene oxide (GO), inhibiting the self-aggregation of naphthalocyanine molecules and graphene, thereby improving electrical conductivity. 25 Herein, we present a novel strategy to directly carbonize metallo-organic molecules to metal-oxide microcrystal/carbon composites, which simultaneously incorporates a facile process and optimized structural design. Specifically, a two-step method is used to anchor ZnNc on GO to obtain a precursor, which is then transformed into ZnO microcrystals on N-doped graphene (denoted as ZnNc/GO-5) after a simple carbonization treatment.…”

Transition metal oxides are a potential anode material owing to their high theoretical capacity. Nonetheless, their large volume changes and low electrical conductivities lead to poor cycling performance and rate capabilities. In this article, an effective strategy is proposed and developed for preparing a ZnO/N-doped graphene composite (ZnNc/GO-5). The key point of this strategy is to use zinc tetra tert-butyl-naphthalocyanine (ZnNc) as a codoped source of N atoms and zinc ions, and graphene oxide (GO) which is combined with ZnNc by π–π deposition as a carbon matrix. After calcination, ZnO microcrystals coated with N-doped graphene are obtained. The unique features of the composite and synergistic effect between N-doped reduced graphene oxide and ZnO microcrystals enable good electrochemical performance by the composites when used in lithium-ion batteries. As an anode material, the as-synthesized ZnNc/GO-5 composite delivers a high first capacity of 1942.9 mAh g–1 and excellent cyclic stability of 861.4 mAh g–1 after 150 cycles at 100 mA g–1. This strategy may offer a new method of designing the anode materials of lithium-ion batteries and promote the practical use of organic molecules in next-generation lithium-ion batteries.
