specific Embodiment approach 1

[0009] Specific Embodiment 1: The method for large-scale synthesis of ZnO nanorod arrays in this embodiment is achieved through the following steps: 1. After mixing zinc acetate and hexamethylenetetraammonium, add it to deionized water, stir and dissolve for 20 to 40 minutes, and then Then add ammonia, stir to obtain a mixed solution, wherein the mol ratio of zinc acetate and hexamethylenetetraammonium is 1: 1, the mol ratio of ammonia and zinc acetate is 0.2: 1, the molar weight of zinc acetate and the volume of deionized water The ratio is 1mol: 6L; 2. Put the zinc flakes in absolute ethanol and ultrasonically clean them for 20-40min; Heating to 120-150° C., keeping it warm for 6-8 hours, then cooling naturally, taking out the zinc sheet, washing with deionized water and drying to obtain the ZnO nanorod array.

[0010] The dosage of the mixed solution in Step 3 of this embodiment only needs to submerge the zinc sheet.

[0011] The method of this embodiment is simple and eas...

specific Embodiment approach 2

[0017] Embodiment 2: The difference between this embodiment and Embodiment 1 is that in Step 1, stir and dissolve for 30 minutes to obtain a mixed solution. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0018] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that in step 2, a digitally controlled ultrasonic cleaner of model KQ2200DB is used for ultrasonic cleaning with an ultrasonic power of 50% to 99% of the rated power. Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

Description

technical field [0001] The invention relates to a method for synthesizing a ZnO nanorod array. Background technique [0002] ZnO is an important wide-bandgap semiconductor material. In addition to its excellent optical and electrical properties, it also combines piezoelectric properties, hydrogen storage properties, pyroelectric properties, field emission properties, and gas-sensing properties. , so that it has a wide range of applications in the fields of chemistry, biosensing, solar cells, photocatalysis, frequency converters, optoelectronics, and flat panel displays. The preparation methods of one-dimensional ZnO nanostructures mainly include gas-phase method and liquid-phase method. Gas-phase synthesis generally requires high temperature and expensive equipment, and the yield is low, and the reaction parameters have a great influence on the final morphology. The hydrothermal method is widely used because of its simple equipment required, low reaction temperature, conve...
