3, nano-copper oxide at room temperature, the application of sorbent: Harbin Institute of Technology to apply the "application of nano-copper oxide and its preparation method," Patent No. CN 200710071896.2, pointed out that the nano-copper oxide (VK-Cu01, 99.9%) at room temperature desulfurization agent can be used as the only component. The nano-copper oxide at room temperature 25-30 ℃ and high precision under the conditions of desulfurization, sulfur capacity of up to 18.3% -28.7%. AR under the same conditions than the copper oxide sulfur capacity of 4.-65 times that of zinc oxide sulfur capacity of 4-8 times that of the preferred temperature desulfurization agent.
4, copper oxide nanoparticles in mesoporous sorbent applications: Shanghai University of application, patent No. CN 200810041467.5 introduced by impregnation of copper oxide nano VK-Cu01 uniform load to the mesoporous materials, prepared with nano-copper oxide sorbent super H2S removal capacity, and to avoid runaway phenomenon, this new type of nano-copper oxide sorbent will replace the commonly used iron oxide and zinc oxide desulfurization sorbent.
5, nano-copper oxide in antimicrobial applications for: Qufu Normal application of the "copper oxide nano-antibacterial agent of a preparation method," Patent No. CN 200810016322.X which states that the copper oxide nanoparticles on Staphylococcus aureus and Bacillus subtilis were compared with good antibacterial activity. The copper oxide nano-antibacterial agent with a clean, efficient, low energy consumption and pollution. Is a new antibacterial agent can be widely used in pharmaceutical, textile and other fields.
6, nano-copper oxide in the feed of: chicken feed in the nano copper oxide, copper oxide nano crude protein and trace elements copper, zinc, iron, manganese and apparent digestibility. The results showed that: in the broiler diet containing copper oxide nanoparticles can significantly improve the apparent digestibility of copper.
7, copper oxide nano-particle energy booster cooler National Institute of Standards and Technology (NIST) researchers Make Ken in the "Examples of nano-copper oxide booster refrigerator energy" in such records: The standard lubricant and refrigerant adding an appropriate amount of the mixture of different nano-particles found in ordinary polyester lubricant on the full diameter of 30nm dispersed copper oxide particles VK-Cu01, and with ordinary refrigerant (R134a) mixed, it can draw cooler heat transfer increased by 50 -275%.
8, copper oxide nano-frozen oil viscosity: To improve the cooling system can be put, reducing air conditioning energy requirements, we found oil in the freezer to add nano-copper oxide (VK-Cu01) particles can reduce the refrigeration oil viscosity and improve the energy efficiency of refrigeration systems. And at a temperature lower than 45 ℃, surfactant + oil + pure copper oxide nano-particles of the stability of the best and most suitable for the viscosity at this time the use of freezer.
9 CuO/Al2O3 cordierite honeycomb catalyst flue gas denitrification performance "CuO/Al2O3 cordierite honeycomb catalyst" of the invention that is coated with nano-alumina in the VK-L30 cordierite honeycomb carrier supported nano CuO (VK -Cu01), obtained cordierite honeycomb catalyst CuO/Al2O3; which Al2O3 catalyst for the stability of the load on the denitrification activity was not affected, but the stability of denitrification, Al2O3 load greater denitrification activity of the catalyst more stable; CuO only load vector in the Al2O3 layer, the catalyst was higher denitrification activity, CuO loading on the stability of the catalyst affect the denitrification activity, when highly dispersed CuO, the stable denitrification activity increased with the increase of CuO loading increased
10, United States Patent US 6,221,275 invented a way to improve the performance of nano-liquid heat to copper oxide nano-VK-Cu01, add 5% of the volume fraction of nano-copper oxide nanoparticles can improve the heat transfer liquid 60 %.
