Embodiment 1
[0033] Step A, liquid phase stripping of black phosphorus:
[0034] Black phosphorus powder, ethanol, and sodium carboxylate are prepared into a dispersion liquid in a reaction kettle by magnetic stirring at a mass ratio of 100:300:3, and then the ultrasonic probe of the ultrasonic pulverizer is placed in the reaction kettle, and nitrogen gas is introduced. Ultrasonic vibration treatment was performed for 30 minutes in a nitrogen-protected environment, and the black phosphorus was peeled off into black phosphorene through ultrasonic cavitation, which was then filtered and dried;
[0035] Step B, grinding modification:
[0036] Mix the dry black phosphorene obtained in step A with ethylenediaminetetraacetic acid and benzoyl chloride at a mass ratio of 100:10:2 and add them to a drum mill with steel balls as the grinding medium, and grind at low temperature for 30 minutes under a nitrogen protection environment , so that black phosphorene is fully combined with ethylenediamine ...
Embodiment 2
[0041] Step A, liquid phase stripping of black phosphorus:
[0042] Add black phosphorus powder to ethanol, add an appropriate amount of surfactant sodium sulfonate and prepare a dispersion liquid by high-speed stirring, then put the ultrasonic probe of the ultrasonic pulverizer into the agitator, and perform ultrasonic vibration treatment for 30 minutes in a nitrogen-protected environment , the black phosphorus is stripped into black phosphorene by ultrasonic cavitation, and then filtered and dried;
[0043] Step B, grinding modification:
[0044] Mix the dry black phosphorene obtained in step A with diethylenetriaminepentaacetic acid and acrylamide in a mass ratio of 100:10:6) and add it to the grinder, and grind it at low temperature for 60 minutes under nitrogen protection environment to make black phosphorene Fully combined with diethylenetriaminepentaacetic acid, making it difficult to generate superoxide anions, thus hindering the degradation of black phosphorene;

Embodiment 3
[0049] Step A, liquid phase stripping of black phosphorus:
[0050]Add black phosphorus powder to ethanol, add an appropriate amount of surfactant phosphate salt, and prepare a dispersion liquid by high-speed stirring, then put the ultrasonic probe of the ultrasonic pulverizer into the agitator, and perform ultrasonic vibration treatment in a nitrogen-protected environment 10min, the black phosphorus is stripped into black phosphorene by ultrasonic cavitation, and then filtered and dried;
[0051] Step B, grinding modification:
[0052] Mix the dry black phosphorene obtained in step A with citric acid and the stabilizer trichloroacetyl chloride in a mass ratio of 100:20:2 and add them to a conical grinder, and grind at a low temperature for 30 minutes under a nitrogen protection environment to make black phosphorene and The citric acid is fully combined, making it difficult to generate superoxide anions, thereby hindering the degradation of black phosphorene;
