Embodiment 1
[0022] Example 1 Cu-TiO 2 / MoS 2 preparation of
[0023] (1) Add 0.6 g of molybdenum disulfide powder and 0.2 mmol of copper salt to 3 mL of n-butyllithium solution, and stir for 12 hours under nitrogen protection at 60 °C to obtain the reacted solution;
[0024] (2) Wash the reacted solution in step (1) with a non-polar solvent, and then perform ultrasonic treatment in a water bath at 60 °C. After the treatment, wash the treated solution with a non-polar solvent, and dry it in vacuum to obtain copper Intercalated molybdenum disulfide nanomaterials;
[0025] (3) Take 500 mg of copper-intercalated molybdenum disulfide nanomaterials prepared in step (2) and add them to 5 mL of tetrabutyl titanate. After stirring for 1 hour, slowly add 0.5 mL of hydrofluoric acid while stirring, and then Reaction in the reactor at 160°C for 18 hours;
[0026] (4) The reaction product obtained in step (3) was centrifuged and washed three times with ultrapure water and absolute ethanol, and the...
Embodiment 2
[0031] Example 2 Cu-TiO 2 / MoS 2 preparation of
[0032] (1) Add 0.6 g of molybdenum disulfide powder and 1.0 mmol of copper salt to 5 mL of n-butyllithium solution, and stir for 24 hours under nitrogen protection at 30 °C to obtain the reacted solution;
[0033] (2) Use a non-polar solvent to wash the solution after the reaction in step (1), and then perform ultrasonic treatment in a water bath at 30 °C. After the treatment, use a non-polar solvent to wash the treated solution, and dry it in vacuum to obtain copper Intercalated molybdenum disulfide nanomaterials;
[0034] (3) Take 200 mg of copper-intercalated molybdenum disulfide nanomaterials prepared in step (2) and add them to 5 mL of tetrabutyl titanate. After stirring for 1 hour, slowly add 0.6 mL of hydrofluoric acid while stirring, and then Reaction in the reactor at 180°C for 20 hours;
[0035](4) The reaction product obtained in step (3) was centrifuged and washed three times with ultrapure water and absolute et...
Embodiment 3
[0040] Example 3 Cu-TiO 2 / MoS 2 preparation of
[0041] (1) Add 0.6 g of molybdenum disulfide powder and 2.0 mmol of copper salt to 10 mL of n-butyllithium solution, and stir for 48 hours under nitrogen protection at 50 °C to obtain the reacted solution;
[0042] (2) Wash the reacted solution in step (1) with a non-polar solvent, and then perform ultrasonic treatment in a water bath at 50 °C. After the treatment, wash the treated solution with a non-polar solvent, and dry it in vacuum to obtain copper Intercalated molybdenum disulfide nanomaterials;
[0043] (3) Take 10 mg of copper-intercalated molybdenum disulfide nanomaterials prepared in step (2) and add them to 5 mL of tetrabutyl titanate. After stirring for 1 hour, slowly add 0.8 mL of hydrofluoric acid while stirring, and then Reaction in the reactor at 200°C for 24 hours;
[0044] (4) The reaction product obtained in step (3) was centrifuged and washed three times with ultrapure water and absolute ethanol, and the...
