Embodiment 1
[0023] Example 1 Fe-TiO 2 / MoS 2 preparation of
[0024] (1) Add 0.6 g of molybdenum disulfide powder and 0.2 mmol of iron salt to 3 mL of n-butyllithium solution, and stir for 12 hours under nitrogen protection at 60 °C to obtain the reacted solution;
[0025] (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 iron Intercalated molybdenum disulfide nanomaterials;
[0026] (3) Add 500 mg of the iron-intercalated molybdenum disulfide nanomaterials prepared in step (2) into 5 mL of tetrabutyl titanate, and 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;
[0027] (4) The reaction product obtained in step (3) was centrifuged and washed three times with ultrapure water and absolute ethanol, and then vacuum-d...
