چکیده

Few-layered boron carbon nitride nanosheets are synthesized by a simple and environmentally friendly process. The BCN nanosheets have 2-6 atomic layers with high surface area and show enhanced storage performance in lithium batteries, as well as a stable capacity of ~100 mA h g(-1) at 2 A g(-1) for 5000 cycles.

Graphene-analogues Boron Nitride nanosheets with ultrahigh ionic liquid uptake capacity as quasi-solid electrolytes

Inorganic nanoparticles are typically used as electrode materials in lithium batteries. However, to cope with the most challenge that solid electrolytes have low ionic conductivity at room or lower temperatures, here we show graphene-analogues boron nitride (g-BN) nanosheets absorbing a large quantity of ILs as a solid-like electrolyte. The layered g-BN nanosheets have very high specific surfac...

Lignin-assisted exfoliation of molybdenum disulfide in aqueous media and its application in lithium ion batteries.

In this article, alkali lignin (AL)-assisted direct exfoliation of MoS2 mineral into single-layer and few-layer nanosheets in water is reported for the first time. Under optimized conditions, the concentration of MoS2 nanosheets in the obtained dispersion can be as high as 1.75 ± 0.08 mg mL(-1), which is much higher than the typical reported concentrations (<1.0 mg mL(-1)) using synthetic polym...

Oxygen- and Lithium-Doped Hybrid Boron-Nitride/Carbon Networks for Hydrogen Storage.

Hydrogen storage capacities have been studied on newly designed three-dimensional pillared boron nitride (PBN) and pillared graphene boron nitride (PGBN). We propose these novel materials based on the covalent connection of BNNTs and graphene sheets, which enhance the surface and free volume for storage within the nanomaterial and increase the gravimetric and volumetric hydrogen uptake capaciti...
