Embodiment 1
[0029] Polyethylene glycol octylphenyl ether (TritonX-100), n-hexanol and cyclohexane were formulated into two emulsified solutions in a mass ratio of 1:1:1, each of which contained 16.25 g of TritonX-100 and 16.25 g of n-hexanol g, cyclohexane is 16.25g. Add 2.45 mL of aqueous sodium molybdate solution with a concentration of 0.05 mol / L into the emulsified solution under emulsification and stirring, and stir for 30 min to form reverse microemulsion A. Add 2.45 mL of 0.4 mol / L glutathione aqueous solution into the emulsified solution under emulsification and stirring, and stir for 30 min to form reverse microemulsion B. The inverse microemulsion A and B are mixed to obtain the inverse microemulsion C, and C is subjected to microemulsion heat treatment at 120°C for 72 hours, then separated, washed, and dried to obtain nanometer molybdenum disulfide. The prepared nano molybdenum disulfide was characterized by XRD as attached figure 1 Among them, molybdenum sulfide has better c...

[0033] Polyethylene glycol octylphenyl ether (TritonX-100), n-hexanol and cyclohexane were formulated into two emulsified solutions in a mass ratio of 2:1:10, each of which contained 7.50 g of TritonX-100 and 3.75 g of n-hexanol g, cyclohexane is 37.50g. Add 0.245 mL of 0.5 mol / L sodium molybdate aqueous solution into the emulsified solution under emulsification and stirring, and stir for 30 min to form reverse microemulsion A. Add 0.245 mL of L-cysteine aqueous solution with a concentration of 2.0 mol / L into the emulsified solution under emulsification and stirring, and stir for 30 min to form reverse microemulsion B. The inverse microemulsion A and B are mixed to obtain the inverse microemulsion C, and C is subjected to microemulsion heat treatment at 160°C for 24 hours, then separated, washed and dried to obtain nanomolybdenum disulfide.

[0036] Polyethylene glycol octylphenyl ether (TritonX-100), n-hexanol and cyclohexane were formulated into two emulsified solutions according to the mass ratio of 5:1:50, each of which contained 4.35 g of TritonX-100 and 0.87 g of n-hexanol g, cyclohexane is 43.50g. Add 24.5 mL of 0.25 mol / L sodium molybdate aqueous solution into the emulsified solution under emulsification and stirring, and stir for 30 min to form reverse microemulsion A. Add 24.5 mL of glutathione aqueous solution with a concentration of 1.0 mol / L into the emulsified solution under emulsification and stirring, and stir for 30 min to form reverse microemulsion B. The inverse microemulsion A and B were mixed to obtain the inverse microemulsion C, and C was subjected to microemulsion heat treatment at 140°C for 48 hours, then separated, washed, and dried to obtain nanomolybdenum disulfide.
