Embodiment 1
[0016] In a high-pressure reactor with a volume of 50mL, add a certain amount of Li 2 CO 3 Powder, direct commercially purchased WS 2 Powder and 40mL organic solvent benzyl alcohol solution, put the autoclave at 200 o The solvothermal reaction was maintained for 48 hours at C temperature; the reaction product was washed with deionized water, acetone, and absolute ethanol, and collected by vacuum drying, and the resulting product was added to deionized water and NN-dimethylformaldehyde at a volume ratio of 1:1. In the mixed solution of methyl formamide, continuous ultrasonic oscillation for 12 hours, the solution was centrifuged at a speed of 600 revolutions per minute (r / min) for 30 minutes (min), the supernatant was taken, and the obtained supernatant was centrifuged at a speed of 6000 r / min The precipitate was collected for 10 min; then, the precipitate was washed with 3% HCl, deionized water, and absolute ethanol, dried in vacuum and the final product was collected.
