چکیده

A novel 2D hybrid with MoS(2) nanocrystals strongly coupled on nitrogen-enriched graphene (MoS(2)/NG(g-C(3)N(4))) is realized by mild temperature pyrolysis (550 °C) of a self-assembled precursor (MoS(3)/g-C(3)N(4)-H(+)/GO). With rich active sites, the boosted electronic conductivity and the coupled structure, MoS(2)/NG(g-C(3)N(4)) achieves superior lithium storage performance.

Three-Dimensional Fe2O3 Nanocubes/Nitrogen-doped Graphene Aerogels: Nucleation Mechanism and Lithium Storage Properties

We developed a solvothermal-induced self-assembly approach to construct three dimensional (3D) macroscopic Fe2O3 nanocubes/nitrogen-doped graphene (Fe2O3-NC/GN) aerogel as anode materials for lithium-ion batteries (LIBs). The Fe2O3 nanocubes with length of ~50 nm are homogeneously anchored on 3D GN frameworks and as spacers to separate the neighboring GN sheets. Based on intensively investigati...

Free-standing hierarchically sandwich-type tungsten disulfide nanotubes/graphene anode for lithium-ion batteries.

Transition metal dichalcogenides (TMD), analogue of graphene, could form various dimensionalities. Similar to carbon, one-dimensional (1D) nanotube of TMD materials has wide application in hydrogen storage, Li-ion batteries, and supercapacitors due to their unique structure and properties. Here we demonstrate the feasibility of tungsten disulfide nanotubes (WS2-NTs)/graphene (GS) sandwich-type ...
