The invention discloses a GaSe nanomaterial, a liquid phase exfoliation method and application thereof. The method includes mixing gallium selenide and isoacetone to obtain a mixed solution, placing the mixed solution in a water bath, and performing ultrasonic dispersion to obtain an initial dispersion solution , and then add isoacetone to the initial dispersion liquid and place it in a water bath, separate and take the supernatant and carry out secondary ultrasonic dispersion, and then separate and take the supernatant and dry it. Its thickness can be controlled by adjusting the experimental temperature or centrifugal speed. No template is required in the process of preparing materials with different thicknesses. The process is simple and the cost is low. The prepared two-dimensional GaSe nanomaterials have a large number, uniform dispersion, and uniform thickness. , and can control different experimental conditions to fabricate GaSe nanomaterials with different thicknesses as needed. |
