[0045] Further, the nickel-doped molybdenum sulfide material is prepared by a hydrothermal method, and the preparation method includes the following steps:
[0046] (1) Sodium molybdate was dissolved in deionized water, and ultrasonically treated for 30-60mins to mix uniformly to obtain solution A;
[0047] (2) Dissolve thiourea in deionized water, and sonicate for 30-60mins until mixed uniformly to prepare solution B;
[0048] (3) dissolving nickel chloride hexahydrate in deionized water, and ultrasonic treatment for 30-60mins to mix uniformly to obtain solution C;
[0049] (4) Add solution B and solution C dropwise to solution A, and ultrasonically treat for 30-60mins until mixed uniformly to obtain mixed solution D;
[0050](5) Transfer the mixed solution D to a high-pressure reactor, and react at a temperature of 150-300° C. for 20-30 hours to prepare a nickel-doped molybdenum sulfide material.
[0051] Further, the concentration of the solution A is 0.1mol / L~1.0mol / L; t...
