Embodiment 1
[0020] 1. Weigh 0.1mmol manganese acetate (Mn(CH 3 COO) 2 2H 2 O) and 9.9 mmol zinc acetate (Zn(CH 3 COO) 2 2H 2 O) powder; mix the two solid powders, add water to dissolve, and make a 200mL solution. 2. Weigh 20mmol sodium diethyldithiocarbamate (Na-DDTC) powder, add water to dissolve, and make 200mL solution. 3. Mix the above two solutions under stirring at room temperature, and keep stirring at room temperature for 2 hours, then filter the resulting precipitate to obtain the precursor Zn 0.99 mn 0.01 -(DDTC) 2 . 4. Weigh 1.0g precursor Zn 0.99 mn 0.01 -(DDTC) 2 Put it in a crucible, put it in a muffle furnace, heat it at 300°C for 3 hours, and then cool it down to room temperature naturally to get the hexagonal Zn 0.99 mn 0.01 S nano powder. Such as figure 1 , figure 2 As shown, the German Bruker AXS D8 ADVANCE X-ray powder diffractometer (Cu K α radiation, ) to determine the crystal phase of the prepared material; the shape and size of the product were ...

[0025] 1. Weigh 0.3mmol manganese acetate (Mn(CH 3 COO) 2 2H 2 O) and 9.7mmol zinc acetate (Zn(CH 3 COO) 2 2H 2 O) powder; mix the two solid powders, add water to dissolve, and make a 200mL solution. 2. Weigh 20mmol sodium diethyldithiocarbamate (Na-DDTC) powder, add water to dissolve, and make 200mL solution. 3. Mix the above two solutions under stirring at room temperature, and keep stirring at room temperature for 2 hours, then filter the resulting precipitate to obtain the precursor Zn 0.97 mn 0.03 -(DDTC) 2 . 4. Weigh 1.0g precursor Zn 0.97 mn 0.03 -(DDTC) 2 Put it in a crucible, put it in a muffle furnace, heat it at 300°C for 3 hours, and then cool it down to room temperature naturally to get the hexagonal Zn 0.97 mn 0.03 S nano powder. Such as image 3 , Figure 4 As shown, the German Bruker AXS D8 ADVANCE X-ray powder diffractometer (Cu K α radiation, ) to determine the crystal structure of the prepared material; the shape and size of the product we...
Embodiment 3
[0030] 1. Weigh 0.5mmol manganese acetate (Mn(CH 3 COO) 2 2H 2O) and 9.5mmol zinc acetate (Zn(CH 3 COO) 2 2H 2 O) powder; mix the two solid powders, add water to dissolve, and make a 200mL solution. 2. Weigh 20mmol sodium diethyldithiocarbamate (Na-DDTC) powder, add water to dissolve, and make 200mL solution. 3. Mix the above two solutions under stirring at room temperature, and keep stirring at room temperature for 2 hours, then filter the resulting precipitate to obtain the precursor Zn 0.95 mn 0.05 -(DDTC) 2 . 4. Weigh 1.0g precursor Zn 0.95 mn 0.05 -(DDTC) 2 Put it in a crucible, put it in a muffle furnace, heat it at 300°C for 3 hours, and then cool it down to room temperature naturally to get the hexagonal Zn 0.95 mn 0.05 S nano powder. Such as Figure 5 , Image 6 As shown, the German Bruker AXS D8 ADVANCE X-ray powder diffractometer (Cu K α radiation, ) to determine the crystal structure of the prepared material; the shape and size of the product wer...
