Abstract:

As a new type of single element direct-bandgap semiconductor,black phosphorus shows many excellent character-istics due to its unique two-dimensional structure,which has great potential in the fields of photoelectronics,biology,sensing,information and so on.In recent years,many new methods and technologies have been developed for the preparation and application of black phosphorus,such as liquid-phase ultrasonic/shear,high-energy ball milling,electrochemical stripping and plasma assisted stripping to achieve efficient prepa-ration of two-dimensional black phosphorus.A series of physical and chemical methods have been developed to modify the surface of two-dimensional black phosphorus to inhibit its contact with water and oxygen and improve the stability and physical properties(such as photoelectronics) of two-dimensional black pho-sphorus.With the help of heterostructure construction,doping and other ways to change the surface electronic density of states and increase the active sites of black phosphorus,the catalytic activity of two-dimensional black phosphorus materials has been improved.Basing on preparation,surface functionalization and photocatalysis of two-dimensional black phosphorus,the current research status and possible future development direction were summarized.

Key words: black phosphorus, two-dimensional materials, exfoliation, surface functionalization, photoelectrocatalysis
