Ultrathin Graphdiyne Nanosheets Grown Insitu On Copper Nanowires And Their Performance As Lithium-Ion Battery Anodes

A method is presented for the scalable preparation of high-quality graphdiyne nanotubes and ultrathin graphdiyne nanosheets (average thickness: ca. 1.9 nm) using Cu nanowires as a catalyst. For the storage of Li+ ions, the graphdiyne nanostructures show a high capacity of 1388 mA hg(-1) and high rate performance (870 mA hg(-1) at 10 A g(-1), and 449.8 mA hg(-1) at 20 A g(-1)) with robust stability, demonstrating outstanding overall potential for its applications.
