Note: Rhodium  rhodium  is a silvery-white metallic element is highly resistant to corrosion and is highly reflective. It is also used in electrical connections and another application is the production of nitric acid and the use in the hydrogenation of organic compounds.

Palladium is also  one of the chemical elements of the periodic table, which is represented by its short symbol Pd and its atomic number 46. Palladium is one of the rare metals that is found in silver and white. Palladium is a platinum group metal and Compared to other metals, this group has the lowest density and the lowest melting point. This rare metal is obtained more from copper and nickel mines.



Nanoparticles are highly regarded both in industry and in the natural sciences due to their widespread use. While natural materials have fixed physical properties regardless of size, the size of a nanoparticle determines its physical and chemical properties. Therefore, the properties of a substance change as its size approaches the nanoscale and the percentage of atoms on the surface of the material becomes significant. An important feature of all nanostructures is that the number of surface atoms in them is greater than the number of volume atoms. This ratio increases with decreasing nanoparticle size. Therefore, nanoparticle size is an important feature. The range of change in nanoparticle activity depends on the nature and shape of the nanostructure. With  However, if the energy field of nano-energy electromagnetic radiation is comparable if certain range Wavelength changes dramatically with the occurrence of chemical reactions in irradiated materials. The activity of nanoparticles  up to 100 nm will be significant. Nanoparticle surface atoms are not energy compensated. In general, the results of nanoparticle energy growth  can be expressed as the total energy of the atomic surface atoms. The freedom of movement of atoms on the surface of nanostructures is  limited, and only vibrational movements and the movement of electrons are possible. These two electro-kinetic reactions are  interdependent because the displacement of the electron clouds of the atoms inevitably changes the vibrational frequencies of the bonds of the nanoparticle atoms  .



Conclusion :
