Palladium is a chemical element; it has symbol Pd and atomic number 46. It is a rare and lustrous silvery-white metal discovered in 1802 by the English chemist William Hyde Wollaston. He named it after the asteroid Pallas (formally 2 Pallas), which was itself named after the epithet of the Greek goddess Athena, acquired by her when she slew Pallas.
25 Σεπ 2024 · The chief use of palladium, however, is in automobile catalytic converters (often in combination with rhodium); the palladium serves as a catalyst to convert polluting hydrocarbons, carbon monoxide, and nitrogen oxide in the exhaust to water, carbon dioxide, and nitrogen.
Because of its corrosion resistance, a major use of palladium is in alloys used in low voltage electrical contacts. When it is finely divided, palladium forms a good catalyst and is used to speed up hydrogenation and dehydrogenation reactions.
23 Ιαν 2020 · Palladium is a silvery-white metallic element with atomic number 46 and element symbol Pd. In daily life, it's most often found in jewelry, dentistry, and catalytic converters for automobiles. Here is a collection of useful and interesting palladium facts:
11 Ιουλ 2024 · Palladium Chloride is used in catalysis and preparing palladium-based compounds, soluble in water. Equation: Pd+Cl₂ → PdCl₂; 2. Palladium(II) Acetate (Pd(O₂CCH₃)₂) Facilitates organic reactions as a catalyst, especially in C-C coupling processes. Equation: 2 Pd+4CH₃COOH → 2 Pd(O₂CCH₃)₂ + 2H₂; 3. Palladium(II) Oxide (PdO)
