Embodiment 1
[0037] Preparation of Graphene Oxide (GO) / MXene Membranes with a Composite Ratio of 1:1
[0038] Take 1g NaNO 3 Add to the beaker, pour 46mL concentrated H 2 SO 4 , placed in a water bath and stirred, then added 2g flake graphite with a mesh number of 325, cooled to 5°C and stirred for 1h; slowly added 6g KMnO 4 , add in batches for 1 hour; then raise the temperature to 35°C and react for 2 hours, slowly add 92mL deionized water, react at 98°C for 15 minutes, and finally add an appropriate amount of hydrogen peroxide to react for 30 minutes, centrifuge the obtained product, first use 5% HCl Solution cleaning, centrifuging at 4000rpm for 8min three times, pouring off the supernatant, and then washing with deionized water, centrifuging at 8000rpm for 8min three times until the pH is neutral, pouring off the supernatant, and finally centrifuging at 12000rpm for 10min to take The upper layer solution was sonicated for 1 h, freeze-dried to a solid, and 100 mg of graphene oxide s...
