[0043] A kind of preparation method of molybdenum sulfide nano-sheet / titanium dioxide nano-sheet / graphite fiber composite material provided by the invention, the specific steps are as follows:
[0044] Step 1: Take 0.3 grams of graphite fiber, add it to 18 milliliters, 5 moles per liter of hydrochloric acid solution, and sonicate for 10 minutes to prepare the first mixed solution.
[0045] Step 2: Take 3 parts of the first mixed solution, add different amounts of butyl titanate dropwise to the 3 parts of the first mixed solution, and stir thoroughly for 30 minutes to prepare the second mixed solution.
[0046] Step 3: Add 0.35 ml of hydrogen fluoride solution with a mass fraction of 47% to the second mixed solution, and stir thoroughly for 5 minutes to prepare the third mixed solution.
[0047] Step 4: Put the third mixed solution in a hydrothermal reaction kettle, and fully react at 180° C. for 4 hours to prepare the fourth mixed solution.
[0048] Step 5: Filter the fourth ...
Embodiment 1
[0053] Step 1: First, measure 18 milliliters of 5 mol per liter hydrochloric acid solution and 0.3 grams of graphite fibers and mix and stir for 10 minutes to prepare the first mixed solution.
[0054] Step 2: Then measure 0.5 ml of butyl titanate, add butyl titanate dropwise to the first mixed solution, and then stir the solution for 30 minutes by magnetic force to fully mix the solution evenly to prepare the second mixed solution.
[0055] Step 3: Next, measure 0.35 ml of hydrofluoric acid with a mass fraction of 47%, add the hydrofluoric acid dropwise into the second mixed solution, and stir for 5 minutes to prepare the third mixed solution.
[0056] Step 4: The third mixed solution was placed in a hydrothermal reactor, and reacted at 180°C for 4 hours to prepare the fourth mixed solution.
[0057] Step 5: Filter the fourth mixed solution to obtain a precipitate, and ultrasonically clean the obtained precipitate with isopropanol solution (the volume ratio of deionized water...
