Example Embodiment
[0039] Example 1
[0040] 1 g of Ti 3 AlC 2 The powder was dispersed into 20 ml of a 50% hydrofluoric acid solution, left standing at room temperature for 24 hours, and then the precipitate was centrifuged with distilled water for 5 times until the pH of the solution was 5. The precipitate was put into a vacuum drying oven and dried at 80°C for 12 hours to obtain a black powder. Put 0.113 g of SnCl 2 Dissolve in 25 ml of distilled water, then add the resulting black powder to SnCl 2 The solution was stirred at room temperature for 3 hours and continued to be sonicated for 30 minutes to obtain a black suspension. The black suspension was put into a reaction kettle with a polytetrafluoroethylene liner, then the reaction kettle was put into an oven, and the temperature was kept at 130° C. for 5 hours. After natural cooling, the precipitate in the reactor was washed three times with distilled water, the precipitate was placed in a drying box, dried at 80 ° C for 12 hours, and...

[0045] Example 3
[0046] 1 g of Ti 3 AlC 2The powder was dispersed into 20 ml of a 50% hydrofluoric acid solution, left standing at room temperature for 24 hours, and then the precipitate was centrifuged with distilled water for 5 times until the pH of the solution was 5. The precipitate was put into a vacuum drying oven and dried at 80°C for 12 hours to obtain a black powder. Put 2.821 g of SnCl 2 Dissolve in 25 ml of distilled water, then add the resulting black powder to SnCl 2 The solution was stirred at room temperature for 3 hours and continued to be sonicated for 30 minutes to obtain a black suspension. The black suspension was put into a reaction kettle with a polytetrafluoroethylene liner, then the reaction kettle was put into an oven, and the temperature was kept at 130° C. for 5 hours. After natural cooling, the precipitate in the reactor was washed three times with distilled water, the precipitate was placed in a drying box, dried at 80°C for 12 hours, and th...
