The main component of the iridium black catalyst is iridium (Ir), which usually exists in the form of nanoparticles and appears as a black powder. Its crystal structure will affect the catalytic performance, such as crystal orientation, lattice defects and so on are related to the catalytic activity. The nano-sized iridium black particles have a high specific surface area and can provide more active sites.
[Advantage] High catalytic activity: Iridium itself has good catalytic performance, which can significantly reduce the activation energy of the reaction and accelerate the reaction rate in a variety of chemical reactions. For example, in the oxygen evolution reaction of electrolyzed water, the reaction can be carried out at a lower overpotential.
Strong stability: It has excellent chemical stability and thermal stability. It can still maintain the stability of structure and performance under harsh reaction conditions such as high temperature, strong acid and strong alkali, and is not easy to be corroded or agglomerated and sintered.
Good selectivity: It has high selectivity for specific reactions, which can make the reaction proceed in the direction of the target product, reduce the occurrence of side reactions, and improve the purity and yield of the product.
【Application】 Water electrolysis for hydrogen production, fuel cells, organic synthesis, redox catalysis, exhaust gas purification, electronic components, etc.
