example 1
[0042] 1. Preparation of MoS 2 Nanosheets:
[0043] Put 3.8 g of ammonium molybdate and 6.6 g of thiourea into 70 mL of distilled water, and stir them under magnetic force at 30 °C to dissolve them to obtain ammonium molybdate concentration of 0.05 g / mL, thiourea concentration of 0.09 g / mL and molybdenum atoms Add a solution with a molar ratio of 1:4 to the sulfur atom, add 2 mL of HNTs powder at 60 °C to the above mixing system, continue stirring to make the solid-liquid mix evenly, and transfer it to a stainless steel autoclave lined with polytetrafluoroethylene , reacted at 180 °C, 5 rpm for 48 h.
[0044] After the reaction, the system was naturally cooled to room temperature, and the product was washed with 20% hydrofluoric acid aqueous solution and 20% hydrochloric acid aqueous solution to remove the template HNTs, and then washed with deionized water and absolute ethanol for 3 ~5 times, centrifuge, filter, dry at 50 °C for 12 h, and collect the black product after gri...

[0049] 1. Preparation of MoS 2 Nanosheets:
[0050] Put 3.8 g of ammonium molybdate and 4.7 g of thioacetamide into 70 mL of distilled water, and stir them under magnetic force at 40 °C to dissolve them to obtain a concentration of ammonium molybdate of 0.05 g / mL and a concentration of thioacetamide of 0.07 g / mL. mL of a solution with a molar ratio of molybdenum atoms and sulfur atoms of 1:3, add 2 mL of HNTs powder at 80 °C to the above mixing system, continue to stir to make the solid-liquid mix evenly, and transfer it to a polytetrafluoroethylene-lined stainless steel In a high-pressure reactor, react at 220° C. and 10 rpm for 24 hours.
[0051] After the reaction, the system was naturally cooled to room temperature, and the product was washed with 30% hydrofluoric acid aqueous solution and 30% hydrochloric acid aqueous solution respectively to remove the template, and then washed with deionized water and absolute ethanol for 3~ Five times, centrifuge, filter, dry at 60 °...

[0056] 1. Preparation of MoS 2 Nanosheets:
[0057] Put 4.3 g of sodium molybdate and 3.3 g of sodium sulfide in 70 mL of distilled water, and stir them under magnetic force at 60 °C to dissolve them to obtain a concentration of sodium molybdate of 0.06 g / mL, a concentration of sodium sulfide of 0.05 g / mL and molybdenum atoms Add 2 mL of 100 °C HNTs powder to the above mixed system with a molar ratio of 1:2 to the sulfur atom, continue to stir to make the solid-liquid mix evenly, and transfer it to a stainless steel autoclave lined with polytetrafluoroethylene , reacted at 240 °C, 15 rpm for 12 h.
[0058] After the reaction, the system was naturally cooled to room temperature, and the product was washed with 40% hydrofluoric acid aqueous solution and 38% hydrochloric acid aqueous solution respectively to remove the template, and then washed with deionized water and absolute ethanol for 3~ Five times, centrifuge, filter, dry at 80 °C for 24 h, and collect the product after g...
