Abstract

The invention relates to preparation methods for a metal / black phosphorus nanosheet composite material, black phosphorus and black phosphorene, wherein a preparation method for the metal / black phosphorus nanosheet composite material includes: 1) grinding 0.001-1000 g of transition metal powder and 0.001-1000 g of red phosphorus powder in a mortar or a ball mill for 5-60 min to obtain ground powder; 2) loading the ground powder into a carrier container, and placing the carrier container in a reaction chamber; 3) feeding protective gas into the reaction chamber, heating the reaction chamber to 500-1200 DEG C, and maintaining the temperature for 1-24 h; 4) then cooling the reaction chamber to room temperature to obtain the metal / black phosphorus nanosheet composite material. Compared with theprior art, the methods are simple in operation, are safe and environment-friendly, are low in cost, and can be used for producing the metal / black phosphorus nanosheet composite material, black phosphorus and black phosphorene in large scales.

Description

technical field [0001] The invention relates to the technical field of metal / black phosphorus nanosheet composite material, black phosphorus and black phosphorene, in particular to a preparation method of metal / black phosphorus nanosheet composite material, black phosphorus and black phosphorene. Background technique [0002] Black phosphorus is a new type of two-dimensional material following graphene, boron nitride, and transition metal sulfides. It has excellent physical, chemical, and mechanical properties, and has great application potential in various devices. Due to the direct band gap and high electron mobility of single-layer and few-layer BP, it has attracted extensive attention of researchers. Black phosphorus is different from graphene with zero band gap and transition metal sulfides with larger band gap. Few-layer black phosphorene has an adjustable band gap with the number of layers. In the infrared range, this feature makes up for the shortcomings of graphene...
