Document Type and Number:
WIPO Patent Application WO/2019/128247
Kind Code:
A1
Abstract:
A preparation method for bismuthene nanosheets, comprising: (1) dispersing bismuth powder in an organic solvent to obtain a dispersion liquid; (2) carrying out first ultrasonic water bath treatment on the dispersion liquid, and then carrying out ultrasonic probe treatment to obtain a first ultrasonic liquid; then, carrying out second ultrasonic water bath treatment on the first ultrasonic liquid to obtain a second ultrasonic liquid; (3) carrying out ultra-low-speed centrifugation on the second ultrasonic liquid at 2000-4000 rpm; collecting a supernatant liquid; and then carrying out low-speed centrifugation on the supernatant liquid at 5000-7000 rpm, and collecting precipitates, the precipitates being the bismuthene nanosheets.
