Examples
Embodiment 1
[0024] 1) Configure a copper acetate solution with a concentration of 0.1mol / L under magnetic stirring, then add pyrrole with a copper acetate mass of 0.01% to it, and magnetically stir to form solution A;
[0025] 2) Take 6 times the molar mass of copper acetate and add red phosphorus after wet grinding into solution A and continue stirring for 3 hours to obtain a dark red suspension;
[0026] 3) Put the suspension in a hydrothermal reaction kettle with a filling ratio of 60%, and conduct a hydrothermal reaction at 250° C. for 24 hours in a homogeneous reactor with a rotational speed of 10 r / min, and wash the product with absolute ethanol after the reaction;
[0027] 4) The product is then placed in a petri dish, sealed with plastic wrap and pierced, and dried at room temperature in a vacuum oven with a vacuum degree of less than -0.1Mpa to obtain Cu 3 P / CuP 2 nanocomposites.
Embodiment 2
[0029] 1) Configure a copper sulfate solution with a concentration of 0.3mol / L under magnetic stirring, then add pyrrole with a copper sulfate mass of 0.06% to it, and magnetically stir to form solution A;
[0030] 2) Add the red phosphorus after wet milling to 7 times the molar mass of copper sulfate into solution A and continue stirring for 4 hours to obtain a dark red suspension;
[0031] 3) Put the suspension in a hydrothermal reaction kettle with a filling ratio of 65%, and conduct a hydrothermal reaction at 220°C for 18 hours in a homogeneous reactor with a rotational speed of 10r / min, and wash the product with absolute ethanol after the reaction;
[0032] 4) The product is then placed in a petri dish, sealed with plastic wrap and pierced, and dried at room temperature in a vacuum oven with a vacuum degree of less than -0.1Mpa to obtain Cu 3 P / CuP 2 nanocomposites.
Embodiment 3
[0034] 1) Configure a copper nitrate solution with a concentration of 0.5mol / L under magnetic stirring, then add pyrrole with a copper nitrate mass of 0.05% to it, and magnetically stir to form solution A;
[0035] 2) Add the wet-milled red phosphorus that is 8 times the molar mass of copper nitrate into solution A and continue stirring for 5 hours to obtain a dark red suspension;
[0036] 3) Put the suspension in a hydrothermal reaction kettle with a filling ratio of 70%, and conduct a hydrothermal reaction at 250°C for 12 hours in a homogeneous reactor with a rotational speed of 10r / min, and wash the product with absolute ethanol after the reaction;
[0037] 4) The product is then placed in a petri dish, sealed with plastic wrap and pierced, and dried at room temperature in a vacuum oven with a vacuum degree of less than -0.1Mpa to obtain Cu 3 P / CuP 2 nanocomposites.
