Embodiment 1

[0019] Add 500 ml of sodium hydroxide aqueous solution (concentration: 0.01 mol / liter) to the reaction bottle, then add 0.001 mol of cuprous thiocyanate powder (0.123 g), apply ultrasonic waves for 1 hour, filter, wash, and dry to obtain the oxidized Cuprous nanowire material. The crude yield is greater than 80%.

[0020] figure 1 It is the result of XRD analysis, which proves that the main component of the product is cuprous oxide, but also contains a small amount of unreacted cuprous thiocyanate in the product.

[0021] figure 2 is a typical SEM image of cuprous oxide nanowire material, showing random packing of cuprous oxide nanowires. The width of cuprous oxide nanowires is less than 50 nanometers, and the length can reach several micrometers or even longer.

[0022] image 3 The SEM image of the cuprous oxide nanowire material at a higher resolution shows that the width of the nanowire is less than 50 nanometers, and the length has exceeded the imaging range.

Embodiment 2

[0024] Add 500 ml of sodium hydroxide aqueous solution (concentration: 0.02 mol / liter) to the reaction bottle, then add 0.001 mol of cuprous thiocyanate powder (0.123 g), apply ultrasonic waves for 1 hour, filter, wash, and dry to obtain the oxidized Cuprous nanowire material. The crude yield is greater than 75%.

[0025] Figure 4 It is the result of XRD analysis, which proves that the product is cuprous oxide.

[0026] The SEM image of the cuprous oxide nanowire material is similar to Example 1.

Abstract

The invention belongs to the technical fields of nanometer materials and chemical materials, and particularly discloses a cuprous oxide nanowire material and a preparation method thereof. The cuprous oxide nanowire material is obtained by reacting commercially available cuprous thiocyanate powder serving as a precursor with aqueous alkali. A process is simple, and the cuprous oxide nanowire material is easy to produce in batches; the prepared cuprous oxide nanowire material can be widely used as an advanced functional material such as a photoelectric conversion material; in addition, the prepared cuprous oxide nanowire material can also be widely applied to the fields of catalysis, sensors, super capacitors, lithium ion batteries, photoelectric functional devices, large-area electronic devices and the like.

Description

technical field [0001] The invention belongs to the technical field of nanometer materials and chemical materials, and in particular relates to a cuprous oxide nanowire material and a preparation method thereof. Background technique [0002] Among many semiconductor materials, cuprous oxide (Cu 2 O) is a very competitive solar cell material due to its bandgap of 2.17 eV. In addition to being used in photoelectric conversion devices, cuprous oxide has a wide range of uses, including: photocatalysis, sensors, supercapacitors, lithium-ion batteries, and various photoelectric functional devices. People have also developed a variety of methods for preparing cuprous oxide thin films, including cuprous oxide nanocrystalline materials. [0003] Nanowires have attracted extensive attention due to their special geometric shapes, high aspect ratios, and quantum size and surface effects. Such materials tend to have better properties than bulk materials. Therefore, how to prepare cup...
