What is copper oxide(CuO)? How to make it?

Copper oxide(CuO) is an inorganic substance. It is a black oxide produced by copper. It is powdery and hygroscopic. Its chemical formula is CuO. It is insoluble in water but relatively soluble in acid.

copper oxide MANUFACTURER Yosoar (11)

Regarding how copper powder is produced to generate, Kunshan Yosoar, as the product manufacturer, tells you that the method is actually very simple. You only need to heat the detected copper powder at a high temperature, and a layer of it will be formed on the surface of the copper powder.

Is  (CuO) soluble in water?

Copper oxide powder is a product of copper oxidation. It is generally black, in the form of a black powder, and is an oxide.

Generally speaking, the powder is almost insoluble in water. Generally speaking, insoluble matter mainly refers to that the solubility of this substance in a certain solvent at a certain temperature is very small, because the amount of dissolved is very small, so our The saying is insoluble, but absolutely insoluble matter does not exist.

The physical and chemical properties of copper oxide(CuO)

Regarding the physical properties of the powder, there are several points. First, this is a black powder, and the shape is spherical, flake, dendritic, etc. It is a product that is insoluble in water and alcohol, but it is dissolved in dilute acid, ammonium chloride, etc., and it can also be slowly dissolved in ammonia to form a complex.

The chemical properties of the powder have the following aspects. First, carbon reduces. This reacts with carbon. At high temperatures, it can be reduced to copper and carbon dioxide. Second, this and carbon monoxide are heated under heating conditions. , Can generate copper and carbon dioxide, third, this and hydrogen react, mall copper and water. The last one is the reaction of CUO with dilute sulfuric acid or hydrochloric acid to produce salt and water.

What should we pay attention to when transporting and storing copper oxide?

When storing copper oxide nanopowder, keep it in a cool and ventilated place, and keep it away from fire and heat sources. Because it will react with some chemicals, it should be stored separately from reducing agents, alkali metals, and edible chemicals. Don’t confuse it.

When transporting CuO powder, you must first ensure that the packaging of the product is complete. Use special packaging bags for packaging copper oxide nanoparticles chemicals. Ensure that the packaging will not be damaged or leaked during transportation. In addition, oxidation must be prohibited during transportation. For mixed shipments of reducing agents, alkali metals, and edible chemicals that react with copper, protection during transportation must also be protected to avoid exposure to the sun and rain.

Can copper(Ⅱ)oxide be used in the study of anode materials?

As a promising negative electrode material, copper oxide powder has the advantages of easy synthesis, high theoretical specific capacity, high safety, non-toxicity, abundant resources, low cost, and good environmental compatibility. This is the current focus of the development of anode materials for lithium batteries. . The chemical reaction formula of copper lithium storage is as follows: CuO + 2 Li ++2e-⇄Cu+ Li2O

At present, the research direction of this used in anode materials is focused on preparing three-dimensional nanostructured copper oxide particles under alkaline conditions to increase the contact area with the electrolyte, increase the contact surface of the reaction, and improve the reversibility of charging. And discharge. Higher capacitance. Nanostructured electrodes can also make Li + diffusion easier, faster reaction kinetics, more stable structure, and adapt to large strains without severe crushing.

Graphene/CuO composite preparation method At present, based on the preparation method of three-dimensional nanostructured material, the preparation method of graphene/CuO composite material has been synthesized. In the prepared composite material, the copper oxide nanoparticles on the surface of the graphene can be effectively kept adjacent. The dispersibility of graphene sheets and graphene can prevent lithium oxide from agglomerating and crushing during the chemical reaction process of lithium storage. The main preparation methods of graphene/CuO composites are: solvothermal method, one-pot synthesis method, microwave radiation method, self-assembly technology, template method and sol-gel method. 1. Solvothermal synthesis method Solvothermal synthesis method is a chemical reaction that accelerates ion reaction and promotes decomposition under high temperature and high pressure. It is one of the common methods for preparing graphene/CuO composite materials. Researchers add urea (CH4N2O) as a blowing agent during the hydrolysis of copper nitrate to obtain rod-shaped      , then add graphene oxide, mix and stir, and then place it in a high temperature and pressure cooker for hydrothermal synthesis reaction to prepare graphene composite material. The porous structure of rod-shaped copper oxide is uniformly attached to the surface of graphene, and CuO nanorods have creeping pores, which accelerate the electron transfer speed of the active material during charging and discharging.

The advantages of the solvothermal synthesis method are: the process is simple, the reaction time is short, and the prepared composite material matrix has good dispersion. The disadvantage is that it is easy to adsorb solution ions. In addition, nano-copper oxides usually grow hydrothermally under alkaline conditions, and the OH concentration is too high, and even Cu(OH)2 precipitates. At present, the research direction of preparing graphene/CuO composites by solvothermal synthesis method tends to add some surfactants to the reaction solution to reduce the appearance of copper hydroxide flocs, and at the same time, it can also adjust the growth rate of different crystals. Plane to obtain a specific structure. Graphene/CuO nanomaterials.

Can copper oxide catalyze the reduction of DNMA by zero-valent iron?

Yes,nitrosodimethylamine (NDMA) has a high risk of causing cancer. Researchers in the drinking water industry have increased the risks and concerns of this type of water after it was discovered in a drinking water plant in one country and in a drinking water well near a rocket engine test site in another country. Subsequent investigations showed that it was produced in water after chlorine, chloramine disinfection and ozone oxidation. Some countries in Europe and Asia have also successively inspected source water, wastewater from drinking water plants and wastewater from sewage treatment plants. In view of the widespread existence of NDMA in water bodies, it is necessary to find effective technology to control it.

The reduction technology of zero-valent iron has attracted wide attention due to its wide variety of raw materials and easy operation. It is used to remove pollutants in the environment, including various chlorinated organics, azo dyes, nitroaromatic compounds, etc. Iron can reduce and degrade NDMA, but the reaction time is longer, so it is necessary to find a way to increase the reaction rate. (CuO) is present in the corrosion products of copper pipes for domestic water supply and has been used to catalyze the oxidation of propylene and phenol in water. Methane is dechlorinated, so its application in catalytic zero-valent iron reduction NDMA has great potential.

Can copper(Ⅱ)oxide be made into fertilizer to replenish copper?

This is a traditional mineral pesticide. It has the functions of killing insects, sterilizing, fertilizer, wood preservation and regulating plant growth in the field of pesticides.

It has also been observed that copper oxide nanoparticles have a high level of cytotoxicity. . Higher than other transition metal oxides (such as iron oxide, titanium dioxide and zinc oxide).

Compared with other metal oxides, their good performance and low cost have aroused people’s interest in the development of copper(II) oxide nanostructured materials. It is believed that its structure is more effective and stable than the antioxidant copper (I) at room temperature.

According to reports, there are many synthetic methods for preparing nanostructured CuO particles, each of which has its own advantages and disadvantages, including sol-gel, hydrothermal, thermal decomposition, microwave radiation, alcohol heating, and heating. Sonochemical process. In this case, this study proposes a method to synthesize and characterize copper(II) oxide nanoparticles using two different precursors. The co-precipitation synthesis method was chosen because of its simplicity, low reaction rate and low cost.

Under the two reaction conditions, sodium hydroxide (NaOH) was used to generate copper oxide nanoparticles in an alkaline medium. The precursors are copper sulfate (CuSO 4 .5H 2 O) and copper chloride (CuCl 2 .2H 2 O). The synthesis was carried out at a temperature of 50°C and 75°C, and the metal salt concentration was 0.1M and 0.2M. After preparation, copper(II) nanoparticles prepared with copper sulfate as a precursor showed better results (smaller crystallite size). The co-precipitation method is considered suitable for obtaining nanostructured materials, and its advantages are simple, fast and cheap.
