Problems solved by technology

It is true that very sensitive devices can be fabricated by using a single nanoribbon, but in the process of device fabrication, electrodes must be prepared by photolithography and micro-welding by focused particle beams. Expensive large-scale equipment, and more importantly, no matter which method is used to prepare the nanoribbon material, there will be a certain difference in size, and this small difference in structure will

Embodiment 1

[0031] A titanium dioxide nano paper is mainly composed of titanium dioxide nanobelts or titanium dioxide nanobelts and additives.

[0032] The preparation method of the above-mentioned titanium dioxide inorganic nano-paper mainly includes a dispersion-suction filtration-drying process, and the specific preparation process steps are as follows:

[0033] 1) Preparation of titanium dioxide nanoribbons

[0034] Weigh 0.1~0.5g TiO 2 The powder is placed in a stainless steel reaction kettle with 15-20ml or 5-15mol / L NaOH or KOH solution and lined with polytetrafluoroethylene. After stirring with a glass rod, close and tighten the reaction kettle, and place it in a preheated 180 ℃~230℃ oven reaction for 24~72h, after the reaction is completed, naturally cool to room temperature, pour out the product in the kettle, wash with deionized water to obtain sodium titanate nanobelts; Soak in HCl solution for 24 hours, wash with deionized water to obtain titanate nanobelts; heat-treat the ...

Embodiment 2

[0039] The preparation steps are the same as in Example 1, except that 0.01 g of titanium dioxide nanobelts is weighed, placed in 1000 g of water, and ultrasonically dispersed for 1 hour to form a nanobelt suspension.

Embodiment 3

[0041] The preparation steps are the same as in Example 1, except that 0.1 g of titanium dioxide nanobelts is weighed, placed in 1000 g of water, stirred and dispersed for 1 hour, and a nanobelt suspension is formed.

Abstract

The invention relates to a Titania nanometer paper and the preparation method, the key component of the Titania nanometer paper is a Titania nanometer belt or the Titania nanometer belt and additive; the Titania nanometer paper mainly includes the preparation method as follows: dispersing, filtrating and drying. Compared with the common nanometer membrane and the nanometer particle, the nanometer paper has a more predominant performance of simple making method and low cost. The nanometer paper is capable of being widely used in the aspects such as high temperature filtration, electron device and photocatalysis, etc. the invention has the advantages of rational design, simple technics, thin fibre, even aperture, good filtering quality and high temperature performance, in addition, the invention is capable of directly being cut, utilizing the average effect of the nanometer belt performance, fundamentally solving the practicality problem of the single nanometer belt device.

Description

technical field [0001] The invention relates to a titanium dioxide nano-paper and a preparation method thereof, belonging to the field of preparation of inorganic nano-materials. Background technique [0002] Titanium dioxide, as a semiconductor material with various functional properties, has important applications in electronics, photocatalysis, photoelectric conversion, gas sensing and biosensors. At present, titanium dioxide used for the above purposes generally exists in the form of nanoparticles or thin films. Due to the disadvantage of difficult recovery of nanoparticles, the application cost is relatively high. Compared with other forms of nanomaterials, titanium dioxide thin films not only have high preparation temperature , high cost and other disadvantages, and because the device can only use the surface effect, the sensitivity and other properties are greatly reduced compared with one-dimensional and two-dimensional nanomaterials, and cannot be popularized and ap...
