Embodiment Construction

[0021] For further describing the novel graded TiO of the present invention 2 The preparation method of the nanotube array will be further described below in conjunction with the accompanying drawings.

[0022] see figure 1 As shown, a novel hierarchical TiO 2 The preparation method of nanotube array, the steps are as follows:

[0023] ①. Preparation of ZnO hierarchical structure template by electrolytic deposition method 10

[0024] Dissolve 0.0063M zinc nitrate and 0.0063M hexamine (Hexamine) into 200mL deionized water as the electrolyte, connect the ITO substrate to the gold wire of the working electrode, and conduct electrolytic deposition with the same gold wire as the reference electrode (process parameters The deposition voltage is -2.5V, the deposition time is 60 minutes, and the temperature of the electrolyte is 95°C), and then the prepared sample is annealed at 350°C for 30 minutes in an air environment to obtain ZnO nanorods.

[0025] Dissolve 0.0063M zinc nitra...

Abstract

The invention relates to the technical field of preparation of TiO2 nano materials, in particular to a method for preparing a classification TiO2 nanotube array. The method sequentially comprises the treatment steps of preparing a ZnO classification structure mold plate with an electrolytic deposition method, preparing a classification ZnO / TiO2 composite structure, peeling off an ITO substrate, carrying out etching to obtain the classification TiO2 nanotube array and the like. According to the method for preparing the novel classification TiO2 nanotube array, physical characteristics of the prepared classification TiO2 nanotube array are controllable, for example, the physical characteristics of the prepared classification TiO2 nanotube array can be adjusted and controlled by adjusting the size and the like of the classification TiO2 nanotube array if the physical characteristics are controllable. In addition, a substrate transferring method provided with the preparation method can completely remove ZnO in classification TiO2 nanotubes, and therefore the physical characteristics of the classification TiO2 nanotubes can be improved.

Description

technical field [0001] The present invention relates to TiO 2 The technical field of preparation of nanomaterials, specifically relating to a novel graded TiO 2 Preparation method of nanotube arrays. Background technique [0002] In the prior art, the preparation of graded TiO 2 The nanotube approach employs the direct growth of TiO on hierarchical ZnO structures 2 Etching ZnO at the same time, so there is a shortcoming that ZnO can not be etched, that is, in TiO 2 ZnO remains in the nanotubes, therefore, will seriously affect the TiO 2 properties of nanotubes and limit their applications. Contents of the invention [0003] Aiming at the technical problems existing in the prior art, the object of the present invention is to provide a novel graded TiO with controllable physical properties 2 Preparation method of nanotube arrays. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a novel graded TiO 2 The prepara...
