The chemical reduction method of silver coated copper powder refers to the process of using a reducing agent to reduce the ions in the main salt to elemental form and depositing on the surface of the substrate with autocatalytic ability in a metastable solution system. When the reducing agent is oxidized on the catalytically active surface, free electrons are generated. These free electrons can re...

Cu is a transition metal and has a special electronic structure and electronic gain and loss properties that are different from other metals. It can show good catalysis for different chemical reactions and is widely used in the field of catalysts. When the size of CuO particles is as small as nanometers, due to the special characteristics of multiple surface free electrons and high surface energy ...

The displacement reaction method is a common process for processing silver-coated copper powder. Because the surface activity of copper powder is very large, it is easy to oxidize, so it must be pretreated before coating the copper powder. 1. Put the required amount of copper powder into the pretreatment tank, and then wash with 15% 30% dilute sulfuric acid to keep the pH of the solution at 3 2. W...

Because nano copper oxide CuO is a p-type semiconductor, it has holes (CuO) +, which may interact with the environment and play an antibacterial or antibacterial effect. Studies have shown that nano CuO has good antibacterial ability against pneumonia and Pseudomonas aeruginosa. The antibacterial process of metal oxide nano-copper oxide CuO can be simply described as: under the excitation of light...

Nanomaterials exhibit many exotic properties that traditional materials do not have. The first thing we need to know is that the nanometer (mainly refers to less than 100nm) of the composition of nanomaterials has four major effects: 1. Small size effect The boundary conditions of the crystal periodicity are destroyed; the atomic density near the surface layer of the amorphous nanoparticle decreas...
