Magnetic CoFe(2)O(4) and NiFe(2)O(4) Induced Self-Assembled Graphene Nanoribbon Framework with Excellent Properties for Li-Ion Battery

A magnetically induced self-assembled graphene nanoribbons (GNRs) method is reported to synthesize MFe(2)O(4)/GNRs (M = Co,Ni). It is found that MFe(2)O(4) compounds not only locate on the surface of GNRs but anchor on the interlayers of GNRs in the diameter of less than 5 nm as well. The in situ gr...

description A magnetically induced self-assembled graphene nanoribbons (GNRs) method is reported to synthesize MFe(2)O(4)/GNRs (M = Co,Ni). It is found that MFe(2)O(4) compounds not only locate on the surface of GNRs but anchor on the interlayers of GNRs in the diameter of less than 5 nm as well. The in situ growth of MFe(2)O(4) and magnetic aggregation at the joints of GNRs act as crosslinking agents to solder GNRs to build a nest structure. Additionally, combining GNRs with MFe(2)O(4) helps to improve the magnetism of the MFe(2)O(4). As an anode material for Li(+) ion batteries, MFe(2)O(4)/GNRs can provide high reversible capacity and cyclic stability (1432 mAh g(−1) for CoFe(2)O(4)/GNRs and 1058 mAh g(−1) for NiFe(2)O(4) at 0.1 A g(−1) over 80 cycles).
