Embodiment 1

[0083] Example 1 Preparation of antimony nanosheets and extremely thin antimony nanosheets

[0084] Sodium chloride (NaCl), aluminum chloride (AlCl) 3 ), antimony oxide (Sb 2 o 3 ) and aluminum powder (Al) are placed in the test tube after mixing evenly according to the amount shown in Table 1, and then the test tube containing the substance is reacted in the heater at the temperature shown in Table 1 for 5 hours, and the test tube is taken out after the reaction is completed. After natural cooling, inject 300ml of deionized water into the reacted test tube, then add 30ml of concentrated hydrochloric acid for pickling, finally centrifuge, and use volume ratio deionized water:concentrated hydrochloric acid=1:10 dilute hydrochloric acid 150ml, 150ml to remove Wash with ionized water and 50ml ethanol. After drying, the product is antimony nanosheets.

[0085] The antimony nanosheets prepared above were mixed with 10g·L -1 The concentration is dispersed in ethanol, and ultr...

Embodiment 2-3

[0086] Example 2-3 Preparation of antimony nanosheets and extremely thin antimony nanosheets

[0087] The preparation method of antimony nanosheets is as described in Example 1, except that the dosage of each substance is changed according to Table 2.

[0088] The preparation of thin antimony nanosheets is as described in Example 1.

Embodiment 4-6

[0089] Example 4-6 Preparation of bismuth nanosheets and extremely thin antimony-bismuth nanosheets

[0090] The preparation method of bismuth nanosheet is as described in embodiment 1, and the difference is that antimony oxide is replaced by bismuth oxide (Bi 2 o 3 ), and adjust the amount of each substance as shown in Table 2.

[0091] The preparation of extremely thin bismuth nanosheets (bismuthene) is as described in Example 1.

[0092] Table 1 prepares the raw material and consumption of antimony nanosheet

[0093]

[0094] Table 2 prepares raw materials and consumption of bismuth nanosheets
