Example Embodiment
[0033] [Example 1]
[0034] Dissolve 0.1g of ammonium thiomolybdate solid (ie 10 parts of Mo salt aqueous solution) in 10ml of water, add 12.5ml of benzene (ie add 5 parts of organic solvent) and 10g of surfactant (ie 10 parts of surfactant) to make The mixed solution is heated and stirred, refluxed, the temperature is controlled at 80°C, and the reaction time is 3h. Weigh SiO 2 Sol 10ml, mass fraction is 5% (that is, 10 parts SiO 2 Sol), pour into the mixed solution and stir for 30 min. Put the mixture into a stainless steel reactor, 180 o C reaction 3days. Take out the solid from the kettle, wash with 10% HF solution and centrifuge to obtain mesoporous MoS 2 Nanosphere.
Example Embodiment
[0035] [Example 2]
[0036] Dissolve 0.5g of ammonium thiomolybdate solid (ie 50 parts of Mo salt aqueous solution) in 10ml of water, add 162.5ml of benzene (ie add 65 parts of organic solvent), 0.5g of surfactant (ie add 0.5 part of surfactant), Prepare a mixed solution, heat and stir, reflux, the temperature is controlled at 90°C, and the reaction time is 5h. Weigh SiO 2 Sol 5ml, the mass fraction is 5% (ie 5 parts SiO 2 Sol), pour into the mixed solution and stir for 30 min. Put the mixture into a stainless steel reactor, 260 o C reaction 3days. Take out the solids from the kettle, wash with 40% HF solution, and centrifuge to obtain mesoporous MoS 2 Nanosphere.
Example Embodiment
[0037] [Example 3]
[0038] Dissolve 1.2g of solid ammonium thiomolybdate in 10ml of water, add 110ml of benzene and 2g of surfactant to form a mixed solution, heat and stir, reflux, temperature control at 100°C, and reaction time of 8h. Weigh SiO 2 20ml of sol with a mass fraction of 8%, pour into the mixed solution and stir for 1h. Put the mixture into a stainless steel reactor, 200 o C reaction 3days. Take out the solids from the kettle, wash with 15% HF solution, and centrifuge to obtain mesoporous MoS 2 Nanosphere.
