Facile synthesis of graphene nanoribbons from zeolite-templated ultra-small carbon nanotubes for lithium ion storage

Abstract

One-dimensional graphene nanoribbons (GNRs) are attracting considerable attention due to their extraordinary electronic, magnetic, and optical properties, which have a wide range of applications, but have not met full success owing to the lack of simple and efficient synthetic strategies. Here, we present a facile strategy for the synthesis of graphene nanoribbons by unraveling ultra-small carbon nanotubes. The armchair (2,2) carbon nanotubes with a theoretical diameter of 0.28 nm fabricated in the nanochannels of ZnAPO4-11 (AEL) zeolite crystal can be transformed into graphene nanoribbons by removing the AEL template through alkali and acid chemical treatment. The as-synthesized graphene nanoribbons are N-doped with thickness of two- to seven-layer, have a width of 10-30 nm and length of > 1 µm, which show high performance as an anode material for lithium ion batteries. Moreover, this strategy can be readily scaled up for practical applications requiring bulk quantities of graphene nanoribbons.
