The uses of commonly used precious metal Palladium group catalysts
Palladium is considered a rare metal and makes up only about 1 part per 100 million parts of the earth's crust. Although it is rarely found in pure form, it is considered the 77th most abundant element on earth. Palladium is characterized by its high hydrogen absorption, which makes it used as a catalyst in reduction processes in the form of palladium sponge or palladium black. Unlike other platinum metals, palladium is much less resistant to chemicals. Palladium catalysts are precious metal catalysts made with palladium as the main active component. It is second only to platinum in the platinum metal catalysts. Palladium catalysts show good activity in hydrogenation, oxidation, dehydrogenation, hydrogenolysis reactions, etc. There are two main forms of palladium catalysts: compound and carrier-loaded.
