What is the application details of cuprous oxide nanoparticles CuO2 powder

April 20,2021.
Nano cuprous oxide is a new type of P-type semiconductor material with active hole-electron pairs and good catalytic activity. Because of its unique properties, it has a wide range of applications in many fields.

SAT NANO---Nano cuprous oxide (Cu2O) is a widely used photoelectric material, it is the oxide of monovalent copper, dark red powder. The particle size is 30-50 nanometers and the purity is 99%.

Nano cuprous oxide not only exhibits good catalytic activity, but also has strong adsorption performance, low-temperature paramagnetism, and bactericidal activity. It has application potential in the fields of organic synthesis, photoelectric conversion, new energy sources, water photolysis, dye bleaching, sterilization, and superconductivity.

1. Antibacterial activity of CU2O cuprous oxide nanoparticles
Nano cuprous oxide particles can react with the mercapto group and disulfide bond in the compound to generate the corresponding mercapto copper compound. The sulfhydryl and disulfide bonds play a key role in the normal life activities of microorganisms. Therefore, nano-cuprous oxide can interfere with the biochemical reactions of microorganisms, thereby interfering with their physiological activities, and even inducing their apoptosis. In addition, nano cuprous oxide also has a strong adsorption effect, can be adsorbed on the bacterial cell wall and destroy its cell wall and cell membrane, causing the death of the bacteria.

The researchers used 30-50nm cuprous oxide nanoparticles, using Staphylococcus aureus (S, a) as a model, and found that the inhibitory rates of nano cuprous oxide at concentrations of 5 and 10ug/ml were as high as 71.8% and 96.6. %, showing good antibacterial activity. In addition, it also has a killing effect on Gram-negative bacteria. Nano CU2O-TiO2 composite can induce the apoptosis of human cervical cancer cells.

Nano cuprous oxide particles can also be used as high-efficiency pesticides for pesticides; as anti-fouling primer for ships to prevent marine organisms from adhering to the bottom of ships;

2. The photoelectron conversion properties of nano-CU2O
Nano cuprous oxide has a forbidden band width of 2.17eV, which is one of the few semiconductor materials that can be excited by visible light. It has photoelectric conversion properties and the theoretical conversion rate is as high as 20%.

3. The catalytic activity of cuprous oxide nanoparticles
The earliest researchers have used nano-cuprous oxide for the photolysis of water. Later, the nano-CU2O-nano-CUO complex was used to successfully photo-decompose water and methanol, which may become a valuable method of converting light energy to hydrogen energy.

The feasibility of applying nano-materials to photocatalytic degradation of organics in wastewater has been confirmed. Among many semiconductor photocatalytic materials, nano-Cu2O cuprous oxide has stable chemical properties, high cost performance, and strong oxidizing ability under the action of sunlight. It can completely oxidize organic pollutants in water to produce carbon dioxide and water. Therefore, nano-cuprous oxide is more suitable for the treatment of various dye wastewater.

Nano cuprous oxide is also used in the treatment of organic pollutants, and the degradation rate is as high as 95% in 50 minutes under the optimal catalytic conditions. Its composite materials can further optimize its performance.
Nano CU2O can degrade methyl orange under visible light, and can also photodegrade nitrophenol, used to prepare antifouling coatings, and catalyze the preparation of polymerized carbon nanofibers.

4. Nano CU2O is used in the detector
The enzyme-free nano cuprous oxide current analysis sensor can detect H2O2 and glucose. This detector is expected to be used in the detection of blood sugar, urine sugar, and sewage peroxide, providing a fast and accurate method for disease diagnosis and environmental detection.

5. Fluorescence properties

Nano Cu2O has a small particle size and low band gap energy, can be excited by visible light, and then can transition to a lower energy level to radiate photons, with blue fluorescence activity.
