Embodiment 1
[0022] Example 1: Flower-like binary sulfide Cu 0.85 Zn 0.15 Preparation of S microparticles.
[0023] Synthesis of flower-like microstructured ZnS:
[0024] Accurately weigh 0.4561 g of precursor complex Zn(phen) 2 (H2O) 2 ] 2 L·6H 2 O (phen = o-phenanthroline; L = synthesis of p-toluenesulfonic acid)) into a 50 ml Erlenmeyer flask, add 11 ml of ethylene glycol, and stir until the complex precursor is completely dissolved. Then accurately weigh 0.0381 g of thiourea, and dissolve it in 5 ml of anhydrous ethylenediamine. Then slowly drop the ethylenediamine solution in which thiourea is dissolved into the precursor complex solution, and wait for all the thiourea solution to be added dropwise to the conical flask, then continue to stir for half an hour. Finally, the above solution was transferred to a 23ml stainless steel kettle with a polytetrafluoroethylene liner, and the stainless steel kettle was put into a constant temperature blast drying oven. Heat at 125 degrees ...
Embodiment 2
[0028] Example 2: Flower-like binary sulfide Cu 0.88 Zn 0.12 Preparation of S microparticles.
[0029] The ZnS selected in this embodiment is the same as the ZnS selected in Embodiment 1.
[0030] Select the ZnS material with a flower-like structure as the precursor, put 0.2924g of ZnS powder in 30mL of 0.05mol / L copper sulfate solution, react at room temperature for 10 minutes, then centrifuge, and use a concentration of 1mol / L Wash 3 times with acetic acid solution, 4 times with deionized water, and dry the obtained solid at 70°C for 10 hours to obtain the Cu 0.88 Zn 0.12 Flower-like binary sulfides of S.
[0031] The energy spectrum of the product after treatment with Cu salt solution is as follows image 3 As shown in b, there are both characteristic peaks of Zn and characteristic peaks of Cu appear, and the characteristic peak of Cu is very strong, indicating that the same ions in the solution have indeed exchanged with the zinc element in the solid ZnS particles.

Embodiment 3
[0032] Example 3: Flower-like binary sulfide Cu 0.91 Zn 0.09 Preparation of S microparticles.
[0033] The ZnS selected in this embodiment is the same as the ZnS selected in Embodiment 1.
[0034] Select the ZnS material with a flower-like structure as the precursor, put 2.924g of ZnS powder in 22.5mL of 1mol / L copper chloride solution, react at room temperature for 80 minutes, and wash with 2mol / L hydrochloric acid solution 4 times, washed 3 times with deionized water, and then centrifuged, and the obtained solid was dried at 60°C for 15 hours, and the composition was Cu 0.91 Zn 0.09 Flower-like binary sulfides of S.
[0035] The energy spectrum of the product after treatment with Cu salt solution is as follows image 3 As shown in c, there are both characteristic peaks of Zn and characteristic peaks of Cu, and the characteristic peaks of Cu are very strong, indicating that the same ions in the solution have indeed exchanged with the zinc element in the solid ZnS particl...
