主 题：Graphdiyne Pyrene Nanowall Li-battery
摘 要：Graphdiyne,as the novel carbon allotrope,which is composed of sp^(2)-and sp-hybridized carbon,has exhibited excellent catalytic activity and *** has been applied in series of fields,such as Li-battery,catalyst and energy *** well-defined structures and useful applications of graphdiyne is still full of challenges in material ***,we optimized the synthesis condition of pyrenylgraphdiyne to obtain the nanowall *** with the typical nanosheet structure,the pyrenyl-graphdiyne nanowalls(Pyr-GDY-NWs)have more area for lithium ***-ion battery featuring Pyr-GDY-NWs-based electrode exhibits a high reversible specific capacity up to 1464 mA·h/g,which is triple than that of the commercial *** also used the theoretical calculation to investigate the mechanism of Li storage in *** experiment and theoretical data showed that Pyr-GDY-NWs had the potential application in lithium ***,Pyr-GDY with a defined structure would be applied in energy storage and energy conversion.
