For example, as the most common transition metal oxide, copper oxide is gradually applied to lithium-ion batteries due to its high theoretical specific capacity (674mAh·g-1), simple preparation and low cost. In order to improve CuO as a battery, the conductivity of the electrode as a negative electrode material limits the volume change of the carbon-based active material during the charging and discharging of the battery, thereby improving the reversible capacity, cycle life, and charging and discharging stability of the battery. The carbon core/copper oxide shell composite electrode used in lithium ion batteries, the core is carbon fiber, and the shell is a thin layer of copper oxide. The copper oxide thin layer has an array-type nano-needle structure and a nano-hole structure.

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

Copper oxide 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. As a fungicide and insecticide, copper has been used in the field of pesticides for a long time, but for traditional copper oxide, there are a series of problems such as slow absorption and poor effect.

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 /Copper oxide 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.

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.
