preparation example Construction

[0013] 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.

[0014] 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

[0018] (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 (...

Abstract

The invention discloses a preparation method of a cubic cuprous oxide nano material. The method is characterized by successfully obtaining the cubic cuprous oxide material by using blue vitriol as a copper source and glucose as a reducing agent and using a liquid phase reduction method and a hydrothermal method. The preparation method has the beneficial effects that the raw materials needed for preparation are rich, are low in costs and do not produce wastes; the preparation process is simple and has good repeatability; the prepared cubic cuprous oxide nano material is widely applied to photocatalysis, gas sensitive materials, antibacterial materials and the like.

Description

[0001] This application is a divisional application of an invention patent application with an application date of April 3, 2013, an application number of 201310116746.4, and an invention title of "Preparation Method of Nano Cuprous Oxide". technical field [0002] The invention belongs to the technical field of nanometer material preparation, and in particular relates to a preparation method of various nanometer cuprous oxide particles with different appearances. Background technique [0003] Cuprous oxide is a p-type semiconductor material that responds to visible light, and its band gap is about 2.0eV. It is a rare semiconductor material that can be excited by visible light. Cu 2 O is non-toxic, has low preparation cost, can directly use sunlight to degrade organic matter, does not produce secondary pollutants, and has high theoretical utilization efficiency. It is one of the green catalysts with great development prospects. Cuprous oxide also has broad application prosp...
