[0028] In parts by weight, 30 parts of rice husk fibers with a diameter of 1 mm, 150 parts of tetrabutyl titanate dilution, and 20 parts of acetic acid solution are successively taken. The rice husk fibers with a diameter of 1 mm and tetrabutyl titanate dilution The mixture was poured into a four-necked flask, and at a temperature of 50°C and a stirring speed of 500r / min, the acetic acid solution was added dropwise to the four-necked flask through a dropping funnel at a rate of 5mL / min while stirring at a constant temperature. After the addition, continue to stir and react at constant temperature for 6 hours, then filter to obtain No. 3 filter cake, and wash No. 3 filter cake with deionized water for 6 times, then transfer the washed No. Dry to constant weight under the same conditions to obtain supported nanofibers; then transfer the obtained supported nanofibers into a tube furnace, and feed an inert gas into the tube furnace at a rate of 400mL / min. Under the protection of th...

Abstract

The invention discloses a preparation method of a titanium dioxide nanotube for a solar cell, belonging to the technical field of new energy source materials. The preparation method comprises the following steps: mixing rice husk with water, standing for staling so as to obtain staled rice husk, sterilizing, washing and drying the staled rice husk, and sequentially carrying out alkaline washing and acid pickling, so as to obtain preprocessed rice husk; mixing the preprocessed rice husk with water, freezing, grinding, carrying out vacuum drying so as to obtain nano-rice husk fibers, dispersingthe nano-rice husk fibers into a tetrabutyl titanate diluent, slowly dropwise adding an acetic acid solution, after the dropwise adding of the acetic acid solution is finished, proceeding reaction, filtering, washing, and drying, so as to obtain supported nano-fibers; and slowly heating the supported nano-fibers under the protection of inert gas, carrying out thermal insulation reaction, and carrying out annealing, so as to obtain the titanium dioxide nanotube for the solar cell. The titanium dioxide nanotube has the characteristics of high specific surface area and excellent dye adsorption performance and photocatalytic effect.

Description

technical field [0001] The invention discloses a preparation method of titanium dioxide nanotubes for solar cells, belonging to the technical field of new energy materials. Background technique [0002] Titanium dioxide (TiO 2 ) as a transition metal oxide, in wide bandgap semiconductor materials, is widely used in pigment generation, ointment processing, water splitting, photocatalytic components, and optoelectronics due to its stable and non-toxic characteristics [0003] Conversion, energy storage and other fields. TiO 2 In addition to the anatase and rutile crystal structures in the stable tetragonal system, it also contains brookite structures, and the first two are the most commonly used crystal structures. Since TiO 2 Nanotubes have been successfully prepared, not only because of their one-dimensional nanostructures, which have unique electron transport properties compared to nanoparticle disordered stacking structures, but also compared to other one-dimensional n...
