Problems solved by technology

However, SnO 2 The preparation method of nanotubes is not very mature and perfect, and the one-step preparation of SnO 2 Nanotubes are still hard to come by
At present, the template method is widely used, but most template methods need an external strong acid / alkali as an etchant to remove the template, but this step will not only increase the risk of the experiment and make the experimental steps more cumbersome, but also not conducive to product cleaning , increasing the cost of preparation

Embodiment Construction

[0016] To further illustrate the preparation of paper-based SnO 2 The method for nanotubes, the present embodiment is implemented according to the technical solution of the present invention, and specific implementation methods are given:

[0017] a. The first step is to prepare paper-based ZnO nanorods as in-situ sacrificial templates.

[0018] Whatmanchromatography paper #2 paper from GE Healthcare Worldwide (Pudong, Shanghai, China) was selected as the paper substrate, and it was cut into a rectangle with a size of 3 cm and a width of 1 cm, and a layer of silver was printed on the surface of the paper substrate by screen printing technology. electrode to make it conductive, and the surface was polished smooth; a layer of nano-ZnO seed layer with a thickness of 1-30 nm was deposited on the obtained paper substrate by pulsed laser deposition, and zinc acetate of 10-40 mmol / L was prepared[ Zn(CH 3 CH 2 ) 2 ] aqueous solution and 1~40 mmol / L hexamethylenetetramine (C 6 h ...

Abstract

The invention discloses a method for preparing a paper-based tin dioxide(SnO2) nanotube, and belongs to the field of inorganic material synthesis. The method comprises the following steps: early processing a paper substrate; depositing a ZnO seed layer; growing a paper-based ZnO nano-bar template; growing the paper-based SnO2 nanotube on an in-situ self-etching template. The method has the characteristics that paper with rich raw materials, low price, flexibility and easiness in degradation is selected, and the SnO2 nanotube is prepared based on a self-etching template machine. The method is low in cost, energy-saving and environment-friendly, is prepared from easily available raw materials, provides a new thought for preparation of paper-based SnO2 nanotubes, and lays foundation for construction of subsequent paper-based SnO2 flexible perovskite solar cell devices.

Description

technical field [0001] The invention relates to a paper-based SnO 2 The invention discloses a method for preparing nanotubes, belonging to the field of synthesis of inorganic nanometer materials. Background technique [0002] Tin dioxide (SnO 2 ) is an n-type semiconductor material with a band gap of 3.6 eV, excellent photoelectric performance, ultraviolet absorption performance and light stability, and is widely used in solar cells, lithium-ion batteries and biosensors and other fields. SnO 2 The synthesis methods can be divided into gas-phase method, liquid-phase method and solid-phase method. Among them, the solvothermal method in the liquid-phase method has the characteristics of simple operation, low cost, and good controllability of size and shape. It is an ideal method for preparing SnO 2 Commonly used methods. Up to now, SnO with various morphologies has been prepared 2 Materials, including nanoparticles, nanotubes, nanorods, nanoribbons, etc. Among them, the n...
