Abstract We report on the design and Li-ion battery anode application of N-doped graphene/porous g-C 3 N 4 nanosheets supporting layered-MoS 2 hybrid. Few-layer MoS 2 nanosheets are highly dispersed on the N-doped graphene/porous g-C 3 N 4 nanosheet matrix, forming a two-dimensional multilayered nanostructure. Benefiting from the unique structure, the hybrid nanosheets exhibit superior electrochemical performance, including excellent cycling stability (maintaining 91% capacity after 100 cycles), a high rate capability (retaining 83% capacity from 50 mA g −1 to 500 mA g −1 ), and a considerably large capacity (achieving more than 800 mAh g −1 at 100 mA g −1 ).
