Abstract
- Black phosphorus (BP) has recently attracted intense research interest due to its unique thickness-dependent and anisotropic electronic and photonic properties, and has shown promising potential in nanophotonic, nanoelectronics and energy storage applications. However, the application of BP in practical devices is hindered by its high commercial cost. To further reduce the cost and accelerate the development of BP, a highly efficient preparation strategy for low-cost BP must be found. Herein, we report such a method via a modified chemical vapor transport (CVT) method by replacing high-purity red phosphorus (RP) with a low-purity precursor counterpart. We show that this method can drastically reduce the cost of manufacturing by several orders of magnitude. Furthermore, the BP produced using low-cost RP shows nearly the same crystal quality, high purity, local chemical structure, and electronic properties, compared with those of the high-cost BP prepared by the traditional CVT method. Most importantly, exfoliated phosphorene nanosheets prepared from the low-cost BP exhibit promising hydrogen evolution reaction (HER) activity. Owing to the high quality and high conversion efficiency, the low-cost BP holds promising potential in future scientific research and industrial applications.
