Embodiment 1
[0022] 1. Raw materials: analytically pure ethylenediamine, thiourea, zinc nitrate hexahydrate, cadmium sulfide pentahydrate.
[0023] 2. Take ethylenediamine and water (total 18ml, volume ratio 4:1) in a 50ml autoclave, and magnetically stir for 10 minutes.
[0024] 3. Add 1.5 mmol of zinc nitrate hexahydrate to the stirred mixture, and stir magnetically at room temperature until clear.
[0025] 4. Add 1.5 mmol thiourea to the clarified mixed solution, stir it magnetically for 20 minutes, then seal it and place it in an oven at 180° C. for 10 hours. The reaction kettle was taken out and cooled to room temperature naturally, the reacted product was transferred from the reaction kettle to a centrifuge tube, and the product was subjected to centrifugal separation and ultrasonic washing with water, and repeated 4 times to obtain pure organic-inorganic hybrid nanosheets.
[0026] 5. The prepared organic-inorganic hybrid nanosheets were redispersed in 28.8 ml of ethylenediamine, a...
