Embodiment 1
[0047] Embodiment 1, raw material Ti 3 C 2 Preparation of (MXene)
[0048] First, add Ti to a teflon beaker 3 AlC 2 (MAX phase) 10 parts, and then slowly add 90 parts of hydrofluoric acid in small amounts and several times. After adding, keep stirring for 3 days at an ambient temperature of 30° C. until the complete reaction is complete. Then, centrifugation and multiple water washes were performed until the pH value was close to 7. Then vacuum-drying to obtain black Ti 3 C 2 Base powder.
[0049] Test the Ti obtained in this example 3 C 2 SEM images of substrates, such as figure 2 shown. Depend on figure 2 It can be seen that Ti 3 C 2 The substrate size is in the micrometer scale.
Embodiment 2
[0050] Embodiment 2, "micro-explosive" method prepares Ti 3 C 2 quantum dots
[0051] Put 10 parts of two-dimensional material Ti 3 C 2 Place in a Teflon beaker, pour 50 parts of liquid nitrogen into the beaker and keep at room temperature for 3 minutes. During this process, liquid nitrogen will intercalate the Ti 3 C 2 and with constant evaporation. When the remaining amount of liquid nitrogen in the beaker is very small, quickly add 50 parts of deionized water at 100°C. Since the boiling point of liquid nitrogen is -196°C, extreme temperature differences occur, resulting in 3 C 2 The liquid nitrogen in the interlayer will be rapidly vaporized, and a large amount of deionized water will form a water seal effect, making the Ti 3 C 2 The microscopic accordion-like structure formed a closed space, which in turn caused a "micro-explosion" to obtain an aqueous suspension. The entire process above only takes a few minutes. (Note: If the residual amount of liquid nitroge...
Embodiment 3
[0057] Embodiment 3, "micro-explosive" method prepares Ti 3 C 2 quantum dots
[0058] 20 copies of two-dimensional material Ti 3 C 2 Place in a Teflon beaker, pour 50 parts of liquid nitrogen into the beaker and keep at room temperature for 2 minutes. During this process, liquid nitrogen will intercalate the Ti 3 C 2 and with constant evaporation. When the remaining amount of liquid nitrogen in the beaker is small, quickly add 50 parts of deionized water at 90°C. Since the boiling point of liquid nitrogen is -196°C, extreme temperature differences occur, resulting in 3 C 2 The liquid nitrogen in the interlayer will be rapidly vaporized, and a large amount of deionized water will form a water seal effect, making the Ti 3 C 2 The microscopic accordion-like structure formed a closed space, which in turn caused a "micro-explosion" to obtain an aqueous suspension. The entire process above only takes a few minutes. (Note: If the residual amount of liquid nitrogen is 0, n...
