Method of preparing monoatomic layer black phosphorous by irradiating ultrasound

摘要

A method of preparing monoatomic layer black phosphorous by irradiating an ultrasound includes: putting black phosphorus into a solvent and irradiating the ultrasound; recovering a solution from a solution to which the ultrasound is irradiated; and collecting black phosphorus remaining after the solution has been recovered, putting the black phosphorus into a solvent, irradiating the ultrasound, and recovering a solution.

主权项

1. A method of preparing monoatomic layer black phosphorous, the method comprising:
putting black phosphorus into a solvent for generating a solution; irradiating the solution with ultrasound energy; filtering out a solution portion from the solution to which the ultrasound energy has been applied, the solution portion being a clear solution where the monoatomic layer black phosphorous is dissolved, leaving a remaining black phosphorus portion; and adding the solvent to the remaining black phosphorus portion for generating a second solution, irradiating the second solution with ultrasound energy, and filtering out a second solution portion from the second solution.
