Embodiment 1
[0026] Weigh 0.2 g InNO 3 4.5H 2 O was dissolved in 30 mL of deionized water, and magnetically stirred until it was completely dissolved to obtain a clear and transparent solution; 2- : In 3+ Add 0.197 g thioacetamide (CH 3 CSNH 2 ), continue magnetic stirring until dissolved, and the solution turns light yellow at this time; then add 0.15 g of polystyrene sodium sulfonate (PSS) as a surfactant to the above solution, stir for a while until dissolved; transfer the above mixed solution to water Heat the kettle, then place the hydrothermal kettle in an oven and heat it at a constant temperature of 150°C for 20 h, take out the hydrothermal kettle after the constant temperature reaction is over, discard the supernatant after natural cooling to room temperature, and collect the precipitate; The precipitate was washed 2-3 times with deionized water and absolute ethanol to remove impurities in the precipitate; the washed precipitate was dried at a constant temperature of 60°C for ...
Embodiment 2
[0030] Weigh 0.2 g InNO 3 4.5H 2 O was dissolved in 30 mL of deionized water, and magnetically stirred until it was completely dissolved to obtain a clear and transparent solution; 2- : In 3+Add 0.197 g thioacetamide (CH 3 CSNH 2 ), continue magnetic stirring until dissolved, at this time the solution turns light yellow; then add 0.15 g polystyrene sulfonate sodium (PSS) as a surfactant to the above solution, stir for a while until dissolved; transfer the above mixed solution to water heat the kettle, then place the hydrothermal kettle in an oven and heat it at a constant temperature of 150°C for 12 h, take out the hydrothermal kettle after the constant temperature reaction is over, discard the supernatant after cooling to room temperature, and collect the precipitate; the above precipitate Wash with deionized water and absolute ethanol 2-3 times to remove impurities in the precipitate; dry the washed precipitate at 60 °C for 10 h to obtain yellow In 2 S 3 powder.
