Abstract:

Because of its unique structure and excellent performance,black phosphorus has performed good application prospects in many fields.At present,the application of black phosphorus is still limited by its preparation methods and stripping methods.Liquid phase method is a method of synthesizing black phosphorus under liquid phase conditions,mainly including mercury reflux method,bismuth melting method and solvent thermal method.Liquid phase method can prepare nano black phosphorus in one step,which has the advantages of simple operation,mild reaction conditions and strong controllabi-lity.It is the most likely method to realize the low-cost and controllable preparation of nano black phosphorus at present.The research status of preparation of black phosphorus by liquid phase method was reviewed.The advantages and disadvantages of this method were analyzed and discussed.In view of the problems of poor crystallinity,low yield and instability of the black phosphorus prepared by this method,it was proposed that choosing appropriate solvent and adjusting reaction temperature were expected to prepare a new structure of nano black phosphorous based materials and improve the crystallinity and yield of black phosphorous.At the same time,in the preparation process to achieve in situ doping or formation of composite materials were expected to improve the stability of black phosphorous,and then broadened the application field of black phosphorous and improved the performance of black phosphorous.

Key words: black phosphorus, liquid phase method, mercury reflux method, bismuth melting method, solvothermal method
