Method for preparing zinc sulfide nanopowder

[0032] Example 1

[0033] 4.242 parts of ZnCl 2 ·2H 2 Two solid powders of O and 1.000 parts of sulfur powder are uniformly mixed, then 30.303 parts of hydrochloric acid, 151.515 parts of ethanol, and 363.636 parts of deionized water are added, and the mixture is uniformly mixed by ultrasonic vibration and stirring. The above mixture solution was poured into a polytetrafluoroethylene lined autoclave, and 30.303 parts of 85% hydrazine were added. Heat the above reaction kettle to 200°C for 90 hours, then cool to room temperature and take it out. The reacted solution is filtered through a water-based microporous filter membrane, washed successively with deionized water and absolute ethanol, and separated by filtration to remove impurities and wash until it is neutral. The resultant after washing was dried in a vacuum oven at 70°C to obtain zinc sulfide powder. After testing, the purity of the obtained ZnS is 100%.

[0035] 4.242 parts of ZnCl 2 ·2H 2 Two solid powders of O and 1.000 parts of sulfur powder are uniformly mixed, then 30.303 parts of hydrochloric acid, 151.515 parts of ethanol, and 363.636 parts of deionized water are added, and the mixture is uniformly mixed by ultrasonic vibration and stirring. The above mixture solution was poured into a polytetrafluoroethylene lined autoclave, and 30.303 parts of 85% hydrazine were added. Heat the above reaction kettle to 200°C for 45 hours, then cool to room temperature and take it out. The reacted solution is filtered through a water-based microporous filter membrane, washed successively with deionized water and absolute ethanol, and separated by filtration to remove impurities and wash until it is neutral. The resultant after washing was dried in a vacuum oven at 70°C to obtain zinc sulfide powder. After testing, the purity of the obtained ZnS is 100%.
