Note: according to user requirements of nano particle, we can provide different size products. Application direction: Precious metal Nano - palladium powders - used as catalysts.Catalysis is one of the bases of production and life in modern society. From the exploitation and utilization of fossil energy to the hydrogenation and reorganization of food industry, catalysis has already affected every aspect of human life. The importance of catalysis is needless to say, so the research of catalysis process and the nature of catalysis have never stopped. Nanometer palladium catalyst plays an indispensable role in the reindustrial production. Nano palladium powder, 20-30 nm, 99.99%, supplied in powder or solution form. Production method: There are two main methods to prepare palladium nanoparticles: physical and chemical methods. The preparation process of physical method is complex. The main chemical method is reduction, and the protectant in the reduction process, palladium nanoparticle suppliers, temperature, ph value etc all have an impact on the properties of palladium nanoparticles. The nanoparticles prepared by this method have the advantages of good dispersion and good particle shape. Palladium nanoparticles are widely used in automobile exhaust treatment and fuel cell catalytic electrode. Storage conditions This product should be stored in dry, cool and sealing of the environment, can not be exposure to air, in addition should avoid the heavy pressure, according to ordinary goods transportation. | ||||||||||||||||||
