Production of few-layer phosphorene by liquid exfoliation of black phosphorus.
We report the liquid exfoliation of black phosphorus in N-methyl-2-pyrrolidone to form few-layer phosphorene nanosheets.
متن کاملTriangular Black Phosphorus Atomic Layers by Liquid Exfoliation
Few-layer black phosphorus (BP) is the most promising material among the two-dimensional materials due to its layered structure and the excellent semiconductor properties. Currently, thin BP atomic layers are obtained mostly by mechanical exfoliation of bulk BP, which limits applications in thin-film based electronics due to a scaling process. Here we report highly crystalline few-layer black p...
متن کاملLiquid exfoliation of solvent-stabilized few-layer black phosphorus for applications beyond electronics
Few-layer black phosphorus (BP) is a new two-dimensional material which is of great interest for applications, mainly in electronics. However, its lack of environmental stability severely limits its synthesis and processing. Here we demonstrate that high-quality, few-layer BP nanosheets, with controllable size and observable photoluminescence, can be produced in large quantities by liquid phase...
متن کاملThermodynamics of cellulose dissolution in an imidazolium acetate ionic liquid.
The heat of dissolution of cellulose in one imidazolium acetate ionic liquid was determined experimentally. The value of -132 ± 8 J g(-1) indicates that the dissolution is exothermal thus confirming energetically favourable cellulose-ionic liquid interactions but indicating that an increase in temperature does not thermodynamically favour the dissolution process.
متن کاملThe Role of Water in the Preparation and Stabilization of High‐Quality Phosphorene Flakes
The stability of phosphorene is shown to be degraded by water. However, the presence of a small amount of water allows the synthesis of high-quality material in liquid exfoliation of black phosphorus using dimethylsulfoxide as solvent. A phosphorus/water molar ratio between 1.5 and 14 maximizes the quality of the phosphorene flakes and their stability.
