Abstract

The invention discloses a preparation method of a titanium dioxide nanotube (rod) array. A wet chemical method is adopted in the whole preparation process. The preparation method comprises the following steps of: firstly, preparing a zinc oxide seed crystal layer on conductive glass by using a sol-gel method; then, growing a zinc oxide nanorod array template on the seed crystal layer by using a liquid phase deposition method; and then, converting the zinc oxide nanorod array template into a titanium dioxide nanotube (rod) array by using the liquid phase deposition method to obtain a one-dimensional titanium dioxide nanotube (rod) array. The preparation method has the advantages that (1) compared with other methods such as an anodic oxidation method, the method is simple in process, free of complex equipment and severe environment and capable of preparing the titanium dioxide nanotube (rod) array on the conductive glass directly; and (2) the method can be used for conveniently controlling the diameter and the length of a zinc oxide nanowire and the thickness of a titanium dioxide shell layer.

Description

technical field [0001] The invention relates to a method for preparing a nano-array, in particular to a method for preparing a titanium dioxide nanotube (rod) array. Background technique [0002] Solar cells can directly convert solar energy into electrical energy, and are considered to be the most effective way to utilize solar energy, so they have always been highly valued by countries all over the world. At present, the solar cells that have been practically used are mainly silicon-based solar cells, which have high efficiency and good stability, but their high manufacturing costs limit their large-scale application. Therefore, in addition to improving the commercialization technology of low-cost and high-efficiency silicon-based solar cells, researchers are more actively exploring new solar cells. Among many solar cells, organic-inorganic composite solar cells have both the low cost of organic cells and the high stability of inorganic cells, so they have been widely val...
