Example Embodiment
[0028] Example 1
[0029] 0.006mol of cadmium chloride (CdCl 2 ) was dissolved in 40 mL of distilled water, and 0.006 mol of sodium thiosulfate (Na 2 S 2 O 3 ) and continue stirring for 30 min. Then, the mixed solution was put into a 70 mL polytetrafluoroethylene liner, and the loading amount was 60% of the volume of the polytetrafluoroethylene liner. The liner was put into a stainless steel kettle, and the hydrothermal kettle was put into an oven for hydrothermal reaction at 120° C. for 12 hours. After the reaction was completed, the reaction kettle was taken out and cooled naturally. A bright yellow precipitate appeared in the liner of the reaction kettle. The yellow precipitate was filtered and washed three times with distilled water and absolute ethanol respectively. The obtained product was placed in an oven and dried at 80° C. for 3 hours to obtain cadmium sulfide microspheres. Take 0.1 g of pre-prepared graphene oxide and ultrasonically disperse it in 400 mL of de...

[0030] Example 2
[0031] 0.006mol of cadmium chloride (CdCl 2 ) was dissolved in 40 mL of distilled water, and 0.006 mol of sodium thiosulfate (Na 2 S 2 O 3 ) and continue stirring for 30 min. Then, the mixed solution was put into a 70 mL polytetrafluoroethylene liner, and the loading amount was 60% of the volume of the polytetrafluoroethylene liner. The liner was put into a stainless steel kettle, and the hydrothermal kettle was put into an oven for hydrothermal reaction at 160° C. for 24 hours. After the reaction was completed, the reaction kettle was taken out and cooled naturally. A bright yellow precipitate appeared in the liner of the reaction kettle. The yellow precipitate was filtered and washed three times with distilled water and absolute ethanol respectively. The obtained product was placed in an oven and dried at 80° C. for 3 hours to obtain cadmium sulfide microspheres. Take 0.25 g of pre-prepared graphene oxide and ultrasonically disperse it in 400 mL of d...

[0032] Example 3
[0033] 0.012mol of cadmium chloride (CdCl 2 ) was dissolved in 40 mL of distilled water, and 0.012 mol of sodium thiosulfate (Na 2 S 2 O 3 ) and continue stirring for 30 min. Then, the mixed solution was put into a 70 mL polytetrafluoroethylene liner, and the loading amount was 60% of the volume of the polytetrafluoroethylene liner. The liner was put into a stainless steel kettle, and the hydrothermal kettle was put into an oven for hydrothermal reaction at 140° C. for 12 hours. After the reaction was completed, the reactor was taken out and cooled naturally. A bright yellow precipitate appeared in the liner of the reactor. The yellow precipitate was filtered and washed three times with distilled water and absolute ethanol respectively. The obtained product was placed in an oven and dried at 80° C. for 3 hours to obtain cadmium sulfide microspheres. Take 0.5 g of pre-prepared graphene oxide and ultrasonically disperse it in 400 mL of deionized water to...
