Embodiment Construction

[0015] Example of the method for preparing cuprous oxide nanowires by the reduction method: dissolve 200 mg of polyethylene glycol and a certain amount of cupric chloride 178.5 mg in 200 ml of deionized water, stir with a magnetic stirrer for 10-15 minutes, and wait for the polyethylene glycol After diol dissolves completely, in this solution, dropwise the sodium hydroxide solution of 1.2ml under constant stirring rate, stir 15 minutes to ensure that reaction is thorough and all generate the blue copper hydride precipitation, then under constant stirring rate to 1.5 ml of hydrazine hydrate solution with a concentration of 13.7 mol / l was added dropwise to the blue copper hydroxide precipitation solution. After the blue copper hydroxide precipitate is completely reduced to the red cuprous oxide precipitate, wash the red cuprous oxide several times with deionized water, then filter it, and bake it in a vacuum oven at 55-65°C for 3 hours to remove it. moisture.

Abstract

The present invention relates to a reduction process of preparing cuprous oxide nano-wire. Water soluble resin polyglycol or acrylate and copper chloride are dissolved in deionized water through stirring, sodium hydroxide solution is added dropwise to the solution with stirring to produce blue copper hydroxide precipitate, and hydrazine hydrate solution is then added dropwise to the solution. After the blue copper hydroxide precipitate is reduced into red cuprous oxide precipitate completely, the red cuprous oxide preciptiate is washed with deionized water for several times, filtered and pressure reducing dried to obtain the cuprous oxide nano-wire. The process is simple, needs no complicated technological condition and is suitable for industrial production.

Description

[0001] 1. Technical field The present invention relates to a method for preparing nanowire materials, especially a method for preparing cuprous oxide nanowires by a reduction method. 2. Background technology [0002] The prospect of cuprous oxide nanowires in scientific research and application is extremely broad. Given that excitons can be present in cuprous oxide (Cu 2 O) Coherent propagation in crystals, thus converting photons into excitons. When passing through a low-dimensional (1D) waveguide, there is little scattering and diffraction; while at the other end, excitons are transformed into photons, cuprous oxide nanowires can be fabricated into nanowire optical waveguides. Cuprous oxide (Cu 2 O) is a P-type semiconductor with a direct bandgap of 2eV. It can convert solar energy into electrical energy or chemical energy, and make solar nano-converters or ultra-miniature lithium-ion battery negative electrode materials and so on. Cuprous oxide nanowires are also one of...
