Embodiment 1

[0020] First add 8g of acetic acid into the container, then add 1g of succinic acid, and stir ultrasonically, then add 8g of nitrogen dimethyl acetamide, stir ultrasonically, and finally add 1g of tetrabutyl titanate, mix well and add to the hydrothermal reaction kettle placed in an oven at a temperature of 140° C. for 12 hours, and after the reaction was completed, the reactor was taken out to obtain titanium dioxide nanorods in anatase phase. The nanorods are 300nm long. The SEM image of the prepared sample is shown in figure 1 It can be seen from the figure that the structure of the nanorod is complete and the surface is uniform. The XRD pattern of the prepared material is as follows Figure 4 As shown in the line a, it can be concluded that the obtained product is anatase crystal.

Embodiment 2

[0022] First add 8g of acetic acid into the container, then add 5g of succinic acid, stir ultrasonically, then add 30g of nitrogen nitrogen dimethylacetamide, stir ultrasonically, and finally add 20g of titanium isopropoxide, mix well and add to the hydrothermal reaction kettle , put into an oven to react at 180° C. for 60 h, and after the reaction, take out the reaction kettle to obtain titanium dioxide nanorods in anatase phase. The nanorods are 400nm long. The SEM image of the prepared sample is shown in figure 2 It can be seen from the figure that the structure of the nanorod is complete and the surface is uniform. The XRD pattern of the prepared material is as follows Figure 4 As shown in the b line, it can be concluded that the obtained product is anatase crystal.

Embodiment 3

[0024] First add 8g of acetic acid into the container, then add 1g of succinic acid, stir ultrasonically, then add 30g of nitrogen nitrogen dimethylacetamide, stir ultrasonically, finally add 20g of tetrabutyl titanate, mix well and add to the hydrothermal reaction kettle placed in an oven at 140° C. for 60 hours, and after the reaction was completed, the reactor was taken out to obtain titanium dioxide nanorods in anatase phase. The nanorods are 500nm long. The SEM image of the prepared sample is shown in image 3 As shown, it can be seen from the figure that the modified nanorods have a complete structure and a uniform surface. Its XRD pattern is as follows Figure 4 As shown by line c in the figure, it can be concluded that the obtained product is anatase crystal.

Abstract

The present invention relates to a method for synthesizing anatase titanium dioxide nanorod. The method comprises firstly adding a certain amount of acetic acid in a container, then adding butanedioic acid, ultrasonic agitating, and then adding N,N-dimethyl acetamide, carrying out ultrasonic agitating and finally adding titanium tetrabutoxide, mixing well, adding into a hydrothermal reaction vessel, reacting while heating to obtain anatase titanium dioxide nanorod after the reaction is completed. The titanium dioxide nanorod is a one-dimensional nanorod having anatase crystalline morphology. The anatase titanium dioxide nanorod prepared by the invention has characteristics of controllable size, simple preparation process and low cost. The anatase titanium dioxide nanorod can be used as a working electrode material of dye-sensitized solar cells and quantum dot solar cells.

Description

Technical field: [0001] The invention relates to a method for synthesizing titanium dioxide nanorods, in particular to a method for synthesizing anatase titanium dioxide nanorods. Background technique: [0002] Energy and the environment are two major themes of scientific research in the 21st century. Solving the current increasingly serious energy shortage and environmental pollution problems is an urgent need to improve the quality of life of the people, ensure national security and realize the sustainable development of human society. Battery technology based on solar energy utilization has great application potential in solving energy and environmental problems. TiO 2 Because of its low price, strong oxidation ability (universal), biological and chemical inertness (environmental protection, no secondary pollution), high efficiency and stability (anti-light corrosion and chemical corrosion), it is the most likely new type of solar cell material for industrialization . ...
