    Used in farmland soil

    Nano-copper oxide can affect the soil by reducing the nitrification, denitrification and soil respiration that occur in the soil, which also has an impact on plants.
    During nitrification, soil ammonia is oxidized to nitrate (NO 2-), and then oxidized to nitrite (NO 3 -). The conversion of ammonia to nitrate is carried out by autotrophic bacteria and Achaea, and it is converted to nitrite by Nitrobacter and Nitrobacter. Nitrospira is complete.
    These two processes are necessary for the final release of nitrogen, which allows plants to produce proteins that are essential for their growth. Excessive use of nano-copper oxide in the soil can inhibit or reduce the production of important nitrates. If it is in rough and medium-textured soil, it will be more serious. Nano particles are the most toxic to nitrifying bacteria.

    What are some of the usual applications and usages of copper oxide nanoparticles?

    The usage of copper oxide nanoparticles in catalyst

    Cu is the 29th element. It has some quite amazing properties including an overall special electronic structure and gains and losses electrons and exhibits a good catalytic effect. This is because of the overall large surface area, high reaction activity, no pollution, and strong selectivity, they have shown good catalytic effects in many reactions.

    The application of ultra-fine nano-scale catalysts is indeed an important solution for adjusting the combustion performance of propellants. It is also used in the sector of national defense, ammonium perchlorate (AP) is the high-energy component of composite solid propellants. It occupies 60% to 80% of the AP propellants. Needle-shaped copper oxide having the size of about 30-50 I prepared by spray pyrolysis is linked with the general surface of AP crystals to form composite particles, thereby reducing the thermal decomposition temperature of AP, accelerating the decomposition rate, and the total heat of decomposition will increase.

    The usage of nanoparticles of copper oxide in antibacterial agent

    The powder has a loose porous spherical morphology, and the extremely low-concentration it have good antibacterial effects on Escherichia coli, Pseudomonas aeruginosa, Salmonella, Bacillus subtilis, and Staphylococcus aureus. When the light energy is greater than the bandgap of this(1.2eV), electrons can be excited from the valence band to the conduction band, generating corresponding electron-hole pairs, and reacting with H2O or O2 in the environment to generate strong oxidizing hydroxyl radicals ( • OH) and superoxide anion (O2-) and other active groups. These active groups can penetrate the cell wall of bacteria, chemically react with the organic molecules in the cell, destroy the cell membrane structure, cause the death of the bacteria, and achieve the purpose of antibacterial.

     The application of copper oxide nanoparticles in desulfurization agent

    At present, a large amount of sulfur-containing gases, such as hydrogen sulfide and sulfur oxides, are emitted into the atmosphere during industrial production, causing serious air pollution. Tests have verified that some metal oxides have good desulfurization properties, including CUO nanoparticles, and have good desulfurization effects. copper oxide nanoparticles with different grain sizes have different desulfurization effects; overall the appearance of oxygen vacancies that are observed on the surface of the product and the decrease of electron density around the copper element is beneficial to improve the desulfurization performance; when the difference in specific surface area of it is small, the desulfurization activity The effect of sulfide is not significant, but if the irregular pore distribution formed by the accumulation of particles is narrow, and there are both open and contracted pore structures, it is beneficial to the removal of hydrogen sulfide.

    Nanoparticles of copper oxide are indeed excellent desulfurization products, this is because they can exhibit excellent activity at normal room temperature, and ultimately the removal accuracy of H2S reaches below 0.05 mg•m-3. After optimization, a change is observed in the overall penetration sulfur capacity of copper oxide nanoparticles and it reaches 25.3% at a space velocity of 3000 h-1, which is a bit higher when compared to other similar desulfurization products.

    In terms of sensors, these nanoparticles of copper oxide can also be used as the coating film of the sensor to improve the sensitivity and selectivity of the sensor to carbon monoxide gas.

    A physical sensor as the name indicates is a device that changes or converts general physical quantities such as light, sound, magnetism, or temperature from the outside into electrical signals. Chemical sensors are devices that convert the types and concentrations of specific chemical substances into electrical signals. It is mainly to design chemical sensors by directly or indirectly causing changes in electrical signals such as electrode potential when sensitive materials and molecules, ions, etc. in the measured substance are in contact with each other. Because the external signal can be converted into an electrical signal in order to indicate, the sensor is also very widely used in many fields related to environments such as environmental monitoring, medical diagnosis, and meteorology.

    What is the conventional preparation method of copper oxide nanoparticles?

    The first method is to directly prepare particles and disperse them in the required solvent to obtain a dispersion of copper oxide nanoparticles, and then form a film by spin coating or other methods. This method has the following advantages: (1) You can choose a suitable solution for dispersion; (2) Since it have been formed, high-temperature annealing or even annealing is not required, and it is suitable for flexible devices. However, this method also has certain drawbacks. For example, the poor dispersion of copper oxide in the solution leads to many defects in film formation and lower device efficiency.

    The second method is to prepare the precursor solution of copper oxide nanoparticles, spin-coated the precursor solution into a film, and fire it into copper oxide nanoparticles by calcination.

In the complex precipitation method, a copper salt is firstly reacted with a complexing agent to form a complex, and then reacted with a precipitating agent to obtain a precursor, and then heat-treated to obtain copper oxide nanoparticles. The main synthesis method is to first prepare Cu(NO3)2 into a solution. Under a certain temperature and full stirring, slowly add the complexing agent dropwise to gradually generate the copper complex, and then dropwise add the precipitating agent under constant stirring. So after the completion of the reaction, filter and wash the precipitate.

    What is the hydrothermal method to prepare copper oxide nanoparticles?

    copper oxide nanoparticles are prepared by the use of the hydrothermal method. The hydrothermal process generally uses water as the reaction solvent. It is a method of nucleating, growing, and recrystallizing copper oxide nanometers by nucleating, growing, and recrystallizing metal copper salt and alkali solution in a special closed reactor at a relevant high temperature as well as a high pressure. For example, using Cu(CH3COO)2•H2O and NaOH as raw materials, a simple hydrothermal method is adopted for a one-step reaction to prepare the particles with high yield and uniform size.

    The hydrothermal method, also known as a hydrothermal method, belongs to the category of liquid phase chemistry. It means that the solubility of some hydroxides in water under high temperature and pressure is greater than the solubility of corresponding oxides in water, so the hydroxides are dissolved in water and oxidized at the same time Method of precipitation. The hydrothermal method is characterized by low production cost, high particle purity, good dispersion, good crystal form, and controllability.

    What is the sol-gel method to prepare copper oxide nanoparticles?

    cuo nanoparticles are prepared by the sol-gel method. The sol-gel method is also known as colloidal chemistry. It is to hydrolyze and condense the reactants to form a stable transparent sol system, and then concentrate to form a transparent gel with a three-dimensional network structure. After drying and heat treatment, copper oxide nanoparticles particles can be obtained. The method has a uniform distribution, small particle size, high purity, and can be industrially produced, but the raw material cost is high, also the washing is difficult, and apart from this, the agglomeration during drying is way easier.

    copper oxide nanoparticles MANUFACTURER Yosoar (13)

    The basic steps of preparing copper oxide nanoparticles powder by using the sol-gel method combined with supercritical drying technology are: dissolve the prepared copper salt solution (Cu(NO3)2) in absolute ethanol, and put the ethanol solution of copper salt in ethanol. In a human autoclave, program the temperature rise and control the pressure (the temperature and pressure should be higher than the critical temperature of ethanol 243℃ and the critical pressure 6.38MPa respectively), keep the pressure for a period of time; then slowly deflate, and then ventilate the protective gas (N2) Naturally cooled to room temperature, black fluffy powder is prepared. Using this method, particles with a uniform particle size distribution, no obvious agglomeration, along with an average size of the particle of about 10 nm can be obtained.

    What is the preparation of copper oxide nanoparticles by the microemulsion method?

    cuo nanoparticles are prepared by the microemulsion method. The microemulsion method is a method in which two immiscible solvents are used to form an emulsion under the action of a surfactant, and nano-particles are obtained after nucleation, coalescence, agglomeration, and heat treatment in microbubbles. Microemulsions are usually transparent and isotropic thermodynamically stable systems composed of surfactants, co-surfactants (usually alcohols), oils (usually hydrocarbons), and water (or aqueous electrolyte solutions). The product prepared by the microemulsion method are small in size and controllable, and the reaction conditions are easy to achieve, but the amount of surfactants and solvents consumed is large, the cost is relatively high, and the overall selection of the system is a little bit difficult, and the operating conditions are demanding.

    What is the preparation of copper oxide nanoparticles by laser evaporation?

    copper oxide nanopowder are prepared by the laser evaporation method. The laser evaporation method uses a laser as a heat source to decompose and evaporate the copper salt and then condense it to form nanoparticles. The steps are as follows: the reactant absorbs the energy of the laser and quickly vaporizes to break the chemical bond, and then reacts to form nanoparticles. The preparation process is to directly irradiate the focused laser beam to the cylindrical solid copper acetate target in the reactor. The copper acetate absorbs the laser to heat up, decomposes, and evaporates, and the steam quickly cools down and condenses into nanoparticles, which enter the trap with the carrier gas. It is collected in the vessel. The laser evaporation method has a short reaction time, fast speed, good dispersion of nanoparticles, small particle size, uniform distribution, and almost a single spherical shape, controllable reaction, simple and continuous process, large output, and production The cost is low, and it has good industrial application prospects.

    What is the template method to prepare copper oxide nanoparticles?

    copper oxide nanoparticles MANUFACTURER Yosoar (15)

    CUO nanoparticles are prepared by the template method. The template method uses molecular sieves, membranes, or nanotubes as templates in the reaction to prepare one-dimensional nanostructured nanoparticles.

    Using carbon nanotubes as a template, rod-shaped cuo nanoparticles particles were prepared, this was done with a particle size ranging from 20 nm to 90 nm along with the length of 250 nm to 700 nm. The main process is to prepare polyhedral carbon nanotubes, then weigh a certain amount of the carbon nanotubes, heat them with a nitric acid solution for 24 hours, wash with water, and dry at the temperature of 60°C for 24 hours. Add the treated carbon nanotubes to 50 mL saturated nitric acid. In the copper solution, after reacting for 48 h under stirring, filter, and wash, the sample was dried at 60℃ for 12 h, then calcined in an argon atmosphere for 5 h, and finally calcined in air at 750℃ for 1 h. The carbon nanotubes are removed to prepare copper oxide nanoparticles.

    This preparation method firstly needs to prepare carbon nanotubes, which is costly. However, the particle morphology core size can be controlled, the product size distribution range is wide, and the yield is high. This is a good method for preparing one-dimensional particles.

    Why do we usually need to introduce ultrasound when preparing copper oxide nanoparticles?

    Ordinary copper oxide present is indeed an important industrial product, which has a wide range of applications in the fields of glass, ceramics, printing, and dyeing, and medicine. When it reaches the nanometer level, it has a quantum size effect, surface effect, etc. And is indeed one of the most widely used inorganic materials, the preparation method of copper oxide nanoparticles is also very important.

    We all are aware that ultrasound is a sound wave with a frequency higher than 20000Hz. It has good directivity, strong penetrating ability, easy to obtain concentrated sound energy, and spreads far in the water. The special acoustic cavitation effect of ultrasound provides an important way to prepare materials with special properties. The source of the acoustic cavitation effect in ultrasound is the growth, contraction, and collapse of the tiny bubble nuclei in the system, which leads to local instantaneous high temperature and high pressure, accompanied by strong high-speed micro jets, shock waves, and discharge luminescence. These effects can be controlled. The overall size and the distribution of the particles as well promote the formation of new solid phases and prevent the aggregation of nanoparticles. And because of its advantages such as simple operation, easy control, and high efficiency, ultrasonic technology is widely used to assist the preparation of nanomaterials and has achieved good results.

    In the preparation of CUO nanoparticles, the ultrasonic-assisted method has become an effective method. The assistance of ultrasound can refine particles, promote particle crystal transformation, and improve certain properties of copper oxide nanoparticles.

    The preparation of CUO nanoparticles by the ultrasonic-assisted method breaks through the traditional preparation method. The ultrasonic technology is not only easy to operate but also effectively solves the problem of agglomeration of nanoparticles and promotes the refinement of crystal grains. Similarly, an important transition metal oxide semiconductor material, the excellent performance of CUO nanoparticles also make it show a very broad application prospect in many fields.
