Graphene-supported covalent organic framework nanosheets for high performance aqueous dual-ion batteries.

ABSTRACT: In situ growth of covalent organic framework (COF) nanosheets on substrates like graphene and carbon nanotubes usually leads to significantly enhanced conductivity but is often accompanied by an obvious reduction in crystallinity, thus resulting in non-ideal electrochemical performance. Herein, the hydrothermal condensation of two molecules with aromatic conjugated structures, triphenylene-2,3,6,7,10,11-hexacarboxylic acid (HATNCA) and 1,3,5-tris(4-aminophenyl) triazine (TAPT), on graphene affords a series of graphene-supported 2D COF nanosheets, HT-COF-XGs (X = 10, 20, and 30 wt% of graphene), with controllable thicknesses of 30, 11, and 7 layers. Powder X-ray diffraction (PXRD) analysis reveals the excellent crystalline nature of the nanosheets and further characterization
