Embodiment 1
[0028] 1.1 Heat dodecylamine to 60°C and stir until it becomes liquid. Take 3 mL of liquid dodecylamine and mix it with 1 mL of oleic acid. The resulting mixture is set aside; weigh 0.5 mmol anhydrous zinc acetate and add it to 6 mL In the purified ethylene glycol, stir to obtain a solution, then add a mixture of dodecylamine and oleic acid, mix and stir evenly, and obtain a yellow transparent solution;
[0029] 1.2 Under the protection of nitrogen, the temperature of the yellow transparent solution was raised to 130 °C at a heating rate of 4 °C / min, and the reaction was refluxed for half an hour;
[0030] 1.3 After the reaction, add 10 mL of n-hexane to the reaction solution, stir well, then add 10 mL of ethanol and centrifuge. The product was obtained after repeating this step three times. The morphology of the obtained zinc oxide is as follows figure 2 As shown, it can be seen from the figure that the resulting zinc oxide products are all three-dimensional flower-shaped,...
Embodiment 2
[0032] 2.1 Heat dodecylamine to 60°C, stir until it becomes liquid, take 2mL of liquid dodecylamine, mix it with 2mL of oleic acid, and prepare the mixture for later use; weigh 0.5 mmol anhydrous zinc acetate, add it to 6 mL for purification In the final ethylene glycol, stir to obtain a solution, then add the mixture of dodecylamine and oleic acid, mix and stir evenly, and obtain a yellow transparent solution;
[0033] 2.2 Under the protection of nitrogen, the temperature of the yellow transparent solution was raised to 130 °C at a heating rate of 4 °C / min, and the reaction was refluxed for 30 minutes;
[0034] 2.3 After the reaction, add 10 mL of n-hexane to the reaction solution, stir evenly, then add 10 mL of ethanol and centrifuge. Repeat this step three times to obtain three-dimensional flower-shaped nano-zinc oxide. The obtained three-dimensional flower-shaped nano-zinc oxide is a single crystal, which has a shape similar to half a red pompom flower, wherein the size of...
Embodiment 3
[0036] 3.1 Heat dodecylamine to 60°C and stir until it becomes liquid. Take 2.67 mL of liquid dodecylamine and mix it with 1.33 mL of oleic acid. The resulting mixture is set aside; weigh 0.3 mmol of anhydrous zinc acetate and add it to 6 In mL of purified ethylene glycol, stir to obtain a solution, then add the mixture of dodecylamine and oleic acid, mix and stir evenly, and obtain a yellow transparent solution;
[0037] 3.2 Under the protection of nitrogen, the temperature of the yellow transparent solution was raised to 130 °C at a heating rate of 4 °C / min, and the reaction was refluxed for 30 minutes;
[0038] 3.3 After the reaction, add 10 mL of n-hexane to the reaction solution, stir evenly, then add 10 mL of ethanol and centrifuge. Repeat this step three times to obtain three-dimensional flower-shaped nano-zinc oxide. The obtained three-dimensional flower-shaped nano-zinc oxide is a single crystal, all of which have a shape similar to half a red pompom flower, wherein t...
