Embodiment 1
[0033] TiH 2 , TiC, and Al powders were weighed at a molar ratio of 1:2:1.1, and ball milled for 12 hours to make them evenly mixed. Using a vacuum tube furnace, using high-purity argon as a protective gas, sintering at 1400 ° C for 2 hours to prepare high-purity Ti 3 AlC 2 The bulk material is finally ground into a 325 mesh powder. Ti obtained by grinding 8g 3 AlC 2 For powder, add 320ml of HF with a concentration of 49%, react at 60°C for 24h, wash the reaction product with deionized water and absolute ethanol until the pH of the supernatant is nearly neutral, and dry it in vacuum at 80°C to obtain the original two-dimensional crystal Titanium carbide nanomaterial Ti 3 C 2 T x .
[0034] Weigh 5g of prepared Ti 3 C 2 T x Add 100ml of ammonia water with a mass fraction of 25% to 28%, and use a high-speed shearing machine at a speed of 6000 revolutions per minute to treat Ti 3 C 2 Tx was intercalated and exfoliated for 2 hours to obtain a two-dimensional crystal t...
