Embodiment 1

[0026] (1) Lithium perchlorate was selected as the oxidant, and the AAO template was soaked in 0.1 mol / L lithium perchlorate solution.

[0027] (2) Prepare 0.1 mol / L pyrrole monomer solution and 0.1 mol / L lithium perchlorate solution, and react in the device at 0.65V for 15 minutes to obtain polypyrrole nanotubes deposited in the AAO template.

[0028] (3) Soak the AAO template in (2) in deionized water for 8 hours to remove the residual pyrrole monomer and lithium perchlorate molecules in the pores of the AAO template.

[0029] (4) Prepare 0.05 mol cadmium chloride solution and 0.1 mol / L thioacetamide solution, react at -0.65V for 3 hours, and obtain polypyrrole / cadmium sulfide coaxial nanotube materials deposited in the channels of the AAO template.

[0030] Depend on figure 1 It is learned that it is a linear structure, by figure 2 It is learned that the outer layer material is an amorphous structure, and the inner layer material is a crystalline structure, so it can be ...

Embodiment 2

[0032] (1) Lithium perchlorate was selected as the oxidant, and the AAO template was soaked in 0.1mol / L lithium perchlorate solution.

[0033] (2) Prepare 0.2mol / L pyrrole monomer solution and 0.2mol / L lithium perchlorate solution, and react in the device at 0.70V for 30min to obtain polypyrrole nanotubes deposited in the AAO template.

[0034] (3) Soak the AAO template in (2) in deionized water to remove the residual pyrrole monomer and lithium perchlorate molecules in the pores of the AAO template.

[0035] (4) Prepare 0.05 mol / L cadmium chloride solution and 0.1 mol / L thioacetamide solution, react at -0.60V for 4 hours, and obtain polypyrrole / cadmium sulfide coaxial nanotubes deposited in the channels of the AAO template Material.

[0036] With the above analysis, by image 3 and Figure 4 It can be seen that the prepared nanotube has a coaxial structure, and the thickness of the polypyrrole on the outer wall changes, which is controllable.

Abstract

The invention relates to a polypyrrole / cadmium sulfide coaxial nano tubular material and a preparation method of the polypyrrole / cadmium sulfide coaxial nano tubular material. The polypyrrole / cadmium sulfide coaxial nano tubular material is characterized in that the outer layer is functional polymer material polypyrrole, the inner layer is crystalline semiconductor material cadmium sulfide, and the diameter of the material ranges from 200nm to 300nm. A porous AAO template serves as an auxiliary condition, different deposition parameters are adjusted and controlled through a two-step electrochemical method, the structure of the coaxial material is controlled, the problem that two-phase materials need to be matched in the prior preparation method is solved, and the complexity of the preparation process is reduced effectively.

Description

technical field [0001] The invention relates to a photoelectric material in the field of solar cells and a preparation method thereof, in particular to a polypyrrole / cadmium sulfide coaxial nanotube material and a preparation method thereof. Background technique [0002] The energy crisis in today's society is constantly intensifying the application of new energy materials, and solar energy has been attracting attention as a renewable energy source. In the currently commercialized solar cell market, inorganic crystalline silicon solar cells occupy a dominant position, but problems such as high production costs and complicated processing technology prevent their large-scale popularization and application. Therefore, dye-sensitized solar cells, small organic molecule heterojunction cells, and organic-inorganic hybrid solar cells are derived. Compared with pure organic material solar cells such as organic small molecules and polymers, organic-inorganic hybrid solar cells achie...
