Embodiment 1
[0028] Polyethylene glycol octylphenyl ether (Triton X-100), n-hexanol and cyclohexane were formulated into mixture A, wherein Triton X-100 was 58.75 g, n-hexanol was 48.61 g, and cyclohexane was 79.92 g. Add 6.55 mL of 0.15 mol / L ammonium tetrathiomolybdate aqueous solution B to mixture A under stirring at 500 rpm, and stir for 30 min to form microemulsion C. Add 1.65 mL of hydrazine hydrate solution D with a concentration of 0.56 mol / L to the above microemulsion C, and stir at 500 rpm for 30 min to form microemulsion E. Transfer the microemulsion E into a hydrothermal reaction kettle, the filling volume is 60% of the free volume of the reaction kettle, seal it and stand at 180° C. for 24 hours for crystallization. Cool down to room temperature naturally after taking out the kettle. After separation by filtration, it was washed three times with deionized water and absolute ethanol to obtain a black solid product, which was dried in vacuum at 70° C. for 12 hours to obtain mol...

[0030] Polyethylene glycol octylphenyl ether (Triton X-100), n-hexanol and cyclohexane were formulated into mixture A, wherein Triton X-100 was 58.75 g, n-hexanol was 48.61 g, and cyclohexane was 79.92 g. Add 6.55 mL of 0.15 mol / L ammonium tetrathiomolybdate aqueous solution B to mixture A under stirring at 500 rpm, and stir for 30 min to form microemulsion C. Add 1.65 mL of hydrazine hydrate solution D with a concentration of 1.4 mol / L to the microemulsion C above, and stir for 30 min to form microemulsion E. Transfer the microemulsion E into a hydrothermal reaction kettle, the filling volume is 60% of the free volume of the reaction kettle, seal it and stand at 180° C. for 24 hours for crystallization. Cool down to room temperature naturally after taking out the kettle. After separation by filtration, it was washed three times with deionized water and absolute ethanol to obtain a black solid product, which was dried in vacuum at 70° C. for 12 hours to obtain molybdenum disu...

[0032] Polyethylene glycol octylphenyl ether (Triton X-100), n-hexanol and cyclohexane were formulated into mixture A, wherein Triton X-100 was 58.75 g, n-hexanol was 48.61 g and cyclohexane was 79.92 g. Add 6.55 mL of 0.15 mol / L ammonium tetrathiomolybdate aqueous solution B to mixture A under stirring at 500 rpm, and stir for 30 min to form microemulsion C. Add 1.65 mL of 2.24 mol / L hydrazine hydrate aqueous solution D to the microemulsion C above, and stir at 500 rpm for 30 min to form microemulsion E. Transfer the microemulsion E into a hydrothermal reaction kettle, the filling volume is 60% of the free volume of the reaction kettle, seal it and stand at 180° C. for 24 hours for crystallization. Cool down to room temperature naturally after taking out the kettle. After separation by filtration, it was washed three times with deionized water and absolute ethanol to obtain a black solid product, which was dried in vacuum at 70° C. for 12 hours to obtain molybdenum disulfide...
