Embodiment 1
[0031] Using zinc acetate, ethylene glycol, water and diethanolamine as raw materials, hierarchical 2D ZnO nanodisks were synthesized by ultrasonic method. First weigh 2.195 g Zn(CH 3 COO) 2 2H 2 O was added to a 150 mL beaker, and 60 mL of ethylene glycol and 40 mL of H 2 O and 10 mL diethanolamine were added to the beaker in turn, and stirred continuously for 30 min to make it a uniform solution. Put the probe of the ultrasonic cell disruptor into the beaker, and adjust its power to 300 W, and set the ultrasonic mode to 8 s , the amplitude was 50%, the ultrasonic time was 10 min, after the ultrasonic was finished, the solution was cooled to room temperature, and the white precipitate was collected by centrifugation. Grade 2D ZnO nanodisks.
[0032] The white powder after drying is directly used in the powder diffraction test to judge its crystal form, and the result shows that the prepared product is zinc oxide ( figure 1 , XRD). Using a scanning electron microscope to...
Embodiment 2
[0036] Using zinc sulfate, diethylene glycol, water and diethanolamine as raw materials, 2D hierarchical zinc oxide nanodisks were synthesized by ultrasonic method. First weigh 2.876 g zinc sulfate ZnSnO 4 Add it into a 150 mL beaker, measure 60 mL diethylene glycol, 40 mL H 2 O and 10 mL diethanolamine were added to the beaker in turn, and stirred continuously for 30 min to make it a uniform solution. Put the probe of the ultrasonic cell disruptor into the beaker, and adjust its power to 500 W, and set the ultrasonic mode to 8 s , the amplitude was 70 %, and the ultrasonic time was 10 min. After the ultrasonic was finished, the solution was cooled to room temperature, and the white precipitate was collected by centrifugation. The precipitate was washed with water and alcohol for three times, and dried at 60 °C to obtain a 2D particle composed of nanoparticles. Hierarchical ZnO nanodisks.
Embodiment 3
[0038] Using zinc acetate, 1,2-propanediol, water and diethanolamine as raw materials, 2D hierarchical ZnO nanodisks were synthesized by ultrasonic method. First weigh 0.2195 g Zn(CH 3 COO) 2 2H 2 O was added to a 150 mL beaker, and 60 mL of 1,2-propanediol and 40 mL of H 2 O and 10 mL diethanolamine were added to the beaker in turn, and stirred continuously for 30 min to make it a uniform solution. Put the probe of the ultrasonic cell disruptor into the beaker, and adjust its power to 500 W, and set the ultrasonic mode to 8 s , the amplitude was 50 %, and the ultrasonic time was 1.0 min. After the ultrasonic was finished, the solution was cooled to room temperature, and the white precipitate was collected by centrifugation. The precipitate was washed with water and alcohol three times, and dried at 60 °C to obtain a 2D particle composed of nanoparticles. Hierarchical ZnO nanodisks.
