Embodiment 1
[0028] At 15-25°C, add 3mmol of L-cysteine to a 100mL beaker filled with 20mL of deionized water, stir magnetically at 400rpm for 30min to dissolve L-cysteine and obtain a transparent solution, then add 20mL Deionized water and 2mmol SbCl 3 , stirred at the same speed for 30min to make SbCl 3 Dissolve and obtain a milky white suspension; transfer the obtained milky white suspension to a high-pressure reaction kettle with a capacity of 80 mL and a polytetrafluoroethylene liner, conduct a hydrothermal reaction at 100 ° C for 15 hours, and naturally cool to room temperature; Take out the polytetrafluoroethylene lining, pour off the supernatant inside, wash the bottom sediment into the centrifuge tube with deionized water, centrifuge at 10000rpm for 10min, and then use deionized water at the same centrifugation speed and time Centrifuge three times, and then centrifuge three times with ethanol. After centrifugation, collect the precipitate and dry it under vacuum at 60°C for ...
Embodiment 2
[0030] At 15-25°C, add 3mmol of L-cysteine to a 100mL beaker filled with 20mL of deionized water, and stir magnetically at 500rpm for 30min to dissolve L-cysteine. At this time, a transparent solution is obtained, and then add 30mL deionized water and 2mmol SbCl 3 , stirred at the same speed for 30min to make SbCl 3 Dissolve and obtain a milky white suspension; transfer the obtained milky white suspension to a high-pressure reactor with a capacity of 80mL and a Teflon liner, conduct a hydrothermal reaction at 120°C for 12 hours, and naturally cool to room temperature; Take out the polytetrafluoroethylene lining, pour off the supernatant inside, wash the bottom sediment into the centrifuge tube with deionized water, centrifuge at 10000rpm for 10min, and then use deionized water at the same centrifugation speed and time Centrifuge three times, then centrifuge three times with ethanol, collect the precipitate after centrifugation, and vacuum dry at 60° C. for 6 hours to obtain...
Embodiment 3
[0032] 15~25℃, add 3mmol of L-cysteine to a 100mL beaker filled with 20mL of deionized water, stir magnetically at 300rpm for 30min to dissolve L-cysteine and obtain a transparent solution, then add 30mL to Ionized water and 1 mmol of SbCl 3 , stirred at the same speed for 30min to make SbCl 3 Dissolve and obtain a milky white suspension; transfer the obtained milky white suspension to a high-pressure reactor with a capacity of 80 mL and a polytetrafluoroethylene liner, conduct a hydrothermal reaction at 150 ° C for 10 hours, and naturally cool to room temperature; Take out the polytetrafluoroethylene lining, pour off the supernatant inside, wash the bottom sediment into the centrifuge tube with deionized water, centrifuge at 10000rpm for 10min, and then use deionized water at the same centrifugation speed and time Centrifuge three times, and then centrifuge three times with ethanol. After centrifugation, collect the precipitate, and vacuum-dry at 80°C for 4 hours to obta...
