Embodiment 1
[0025] 1) Dissolve NaCl evenly in 200mL Ti 3 C 2 MXene aqueous solution, wherein the NaCl concentration is 3M, the Ti used 3 C 2 The concentration of MXene aqueous solution is 15g L –1 .
[0026] 2) Place the above-mentioned MXene aqueous solution containing inorganic salts at room temperature to form a long-term stable MXene aqueous solution, wherein the water activity is 0.92, and the dissolved oxygen concentration is 3.67mg L -1 .
[0027] 3) After filtering and washing to remove NaCl, pure Ti can be obtained 3 C 2 MXene.
[0028] 4) Evaporation and crystallization of NaCl from which MXene has been filtered out at 55°C can realize the recovery of NaCl.
[0029] Such as figure 1 As shown, after storage for 30 days under the above conditions, Ti 3 C 2 MXene still maintains its two-dimensional structure, proving its good protective effect.
Embodiment 2
[0031] 1) Dissolve NaCl evenly in 200mL Ti 3 C 2 In the MXene aqueous solution, where the NaCl concentration is 5.5M, the Ti used 3 C 2 The concentration of MXene aqueous solution is 1g L –1 .
[0032] 2) Place the above-mentioned MXene aqueous solution containing inorganic salts at room temperature to form a long-term stable MXene aqueous solution, in which the water activity is 0.76 and the dissolved oxygen concentration is 1.95mg L -1
[0033] 3) After filtering and washing to remove NaCl, pure Ti can be obtained 3 C 2 MXene.
[0034] 4) Evaporation and crystallization of NaCl from which MXene has been filtered out at 55°C can realize the recovery of NaCl.
[0035] Such as figure 2 As shown, after storage for 30 days under the above conditions, Ti 3 C 2 The X-ray diffraction pattern of MXene did not change significantly, proving that its crystal structure was well maintained.
Embodiment 3
[0037] 1) will K 2 SO 4 Uniformly dissolved in 200mL Ti 3 C 2 MXene aqueous solution, where K 2 SO 4 The concentration is 0.6M, the Ti used 3 C 2 The concentration of MXene aqueous solution is 10g L –1 .
[0038] 2) Put the above-mentioned MXene aqueous solution containing inorganic salts at room temperature to form a long-term stable MXene aqueous solution, in which the water activity is 0.96.
[0039] 3) After filtering and washing to remove K 2 SO 4 , to obtain pure Ti 3 C 2 MXene.
[0040] 4) will filter out the K of MXene 2 SO 4 The solution evaporates and crystallizes at 55°C, and K 2 SO 4 recycling.
