Benefits of technology

This technology allows for fast and stable production of cupprostenic acid (CuO) particles without generating excessive material or wasting expensive starting products at once. These Coxoanium dioxides are useful because they exhibit unique properties such as being able to absorb light efficiently by forming an electron cloud around each particle's surface. They also possess specific chemical structures which make them highly effective catalysts against harmful organisms found worldwide.

Problems solved by technology

This patented technical problem addressed in this patents relates to finding ways for producing efficient materials called CuxO (copper zinc oxides) without harmful chemical substances like mercury or other heavy metals. Additionally, it suggests developing new methods for making these materials with controlled shapes such as octaferon, honeycomb core, etc., while avoiding excessive costs associated therewith.

preparation example Construction

[0014] A preparation method of nano-cuprous oxide, the method is specifically: 10mL concentration of 0.05moL / L copper nitrate aqueous solution is dripped into a beaker filled with 50mL deionized water, then adding 0.5mL concentration of 2mol / L copper nitrate NaOH aqueous solution, stirred evenly at room temperature, then added 0.032g hydrazine hydrate, stirred for 40min to obtain a reddish brown precipitate, the product was centrifuged, washed three times with deionized water and absolute ethanol, and placed in a vacuum oven at 60°C Drying for 6 hours under the hood to obtain octahedral cuprous oxide nanomaterials.

[0015] A method for preparing nano-cuprous oxide, the method specifically comprising: dissolving 0.025g of copper sulfate pentahydrate and 0.05g of polyvinylpyrrolidone in 15mL of absolute ethanol, stirring at room temperature for 2 hours to fully dissolve. Then add a mixed solution consisting of 0.072g glucose, 0.032g sodium hydroxide, and 10g water, stir for 20m...

Embodiment

[0019] (1) Octahedral cuprous oxide nanomaterials: 10mL copper nitrate aqueous solution with a concentration of 0.05moL / L is used as a copper source, put it into a beaker filled with 50mL deionized water, and add 0.5mL NaOH aqueous solution with a concentration of 2mol / L Adjust the pH of the solution, stir evenly at room temperature, then add 0.032g hydrazine hydrate as a reducing agent, and stir for 40 minutes to obtain a reddish-brown precipitate. The product is centrifuged, washed three times with deionized water and absolute ethanol, and placed in vacuum drying Dry in an oven at 60°C for 6 hours to obtain octahedral cuprous oxide nanoparticles. figure 1 (a) is a scanning electron microscope picture of octahedral copper oxide nanomaterials. It can be seen from the figure that the obtained octahedrons are uniform in size, with a size of about 300nm. figure 2 The XRD picture of the octahedral cuprous oxide shows that the six peaks in the obtained product correspond to the (1...

Abstract

The invention discloses a preparation method of nano cuprous oxide. In the method, copper chloride and copper nitrate are taken as copper sources, hydrazine hydrate, glucose and an ascorbic acid and the like are taken as reducing agents, and cuprous oxide materials in the shape of an octahedron, a hollow sphere, a cube and a hollow cube and the like are successfully obtained by using a liquid-phase reduction method and a hydrothermal method. Required raw materials for preparation are rich, the cost is low, and no waste is produced. The preparation process is simple, and the repeatability is good. Cuprous oxide nano-materials have wide applications in the aspects of photocatalysis, gas-sensing materials, antibacterial materials, and the like.
