Precious metals refer to some rare and expensive metal materials, such as silver, gold, ruthenium, rhodium, palladium, platinum, iridium and other expensive metals.
Nanomaterials refer to materials at the nanometer level on one-dimensional or multi-dimensional scales, such as nanowires and nanoparticles.
Noble metal nanoparticles are nanomaterials composed of these noble metals, such as gold nanoparticles and nanosilver wires.
The main application areas of nano precious metal particles are as follows:
1) Electronic field.
Silver powder conductive paste has been widely used in many electronic industries such as hybrid integrated circuits and solar cells as the most basic and key functional material.
2) Antibacterial field.
The ultra-fine nano silver powder destroys the proliferation ability of microbial cells through direct or indirect catalysis, causing them to lose their activity, thereby achieving the purpose of sterilization.
3) Industrial catalysis.
Nano platinum group metals are known as the "vitamins" of modern industry. The precious metals such as gold, platinum, palladium, rhodium, etc., because their d-electron orbitals are not filled, reactants are easily adsorbed on the surface to form intermediate products with high reactivity, thereby reducing the activation energy of the reaction and increasing the reaction rate. At present, platinum, palladium and rhodium catalysts have been widely used in many chemical production fields such as automobile exhaust purification devices and petroleum reforming. In addition, noble metal materials play three roles in low-temperature fuel cells: adsorption, electron transport, and surface reaction, thereby greatly improving fuel cell efficiency.
4) Medical applications.
Nano gold has good biocompatibility. The surface-modified gold nanoparticles can play a very important role in many aspects such as drug carriers, cell imaging, DNA labeling, etc.
5) Beauty care
Nano gold and nano platinum are safe, environmentally friendly, non-toxic and tasteless. The application of skin care and beauty is increasing.
