Abstract

The invention provides a preparation method of a zinc oxide nanotube array. The method is characterized by comprising the following steps: cutting a base material into a certain size, and respectively subjecting the base material to ultrasonic treatment in acetone and ethanol for 15min, and taking out the base material and then drying with nitrogen; putting cleaned base material in UV and ozone for 15min to remove the organic substances on the surface; preparing a reaction solution by respectively preparing a zinc salt solution with concentration of 0.01-0.1M and an ammonia solution, a sodium hydroxide solution or a methenamine solution with a concentration of 0.01-0.1M, and mixing the two solution according to a volume ratio of 1:1-5:1; placing the treated base material into the prepared solution, and sealing; placing a sealing bottle containing the reaction solution and the base material in an oven, reacting at 70-105 DEG C for 5-20h, taking out the sample, naturally cooling to room temperature, conducting rinsing with deionized water and performing drying to obtain the zinc oxide nanotube array. The preparation method has the advantages of simple process and flow, good ZnO nanotube array product with uniform thickness, low cost, strong repeatability and synthesis in a large amount.

Description

technical field [0001] The invention relates to a preparation method of a nanotube array, in particular to a preparation method of a zinc oxide nanotube array. Background technique [0002] ZnO is an important multifunctional semiconductor material, which has a wide energy gap (3.37 eV) and high exciton binding energy (60 meV) at room temperature, and its excitons can exist at room temperature and above. Zinc oxide is inexpensive, non-toxic, biodegradable and biocompatible. As an important semiconductor functional material, zinc oxide has excellent thermal stability and unique mechanical, optical, and electrical properties, so it has important applications in electronics, optics, optoelectronics, lasers, and light-emitting diodes. [0003] Zinc oxide possesses piezoelectric and pyroelectric properties, making it one of the most promising candidates for applications in sensors, transducers, generators, and photocatalytic hydrogen production. Therefore, the research on ZnO ...
