Palladium is also used in electronics, dentistry, medicine, hydrogen purification, chemical applications, groundwater treatment, and jewelry. Palladium is a key component of fuel cells, in which hydrogen and oxygen react to produce electricity, heat, and water. Ore deposits of palladium and other PGMs are rare.
Palladium compounds. Palladium forms a variety of ionic, coordination, and organopalladium compounds, typically with oxidation state Pd 0 or Pd 2+. Palladium (III) compounds have also been reported. Palladium compounds are frequently used as catalysts in cross-coupling reactions such as the Sonogashira coupling and Suzuki reaction.
Palladium (II) chloride, also known as palladium dichloride and palladous chloride, are the chemical compounds with the formula PdCl 2. PdCl 2 is a common starting material in palladium chemistry – palladium-based catalysts are of particular value in organic synthesis. It is prepared by the reaction of chlorine with palladium metal at high ...
Organopalladium chemistry is a branch of organometallic chemistry that deals with organic palladium compounds and their reactions. Palladium is often used as a catalyst in the reduction of alkenes and alkynes with hydrogen. This process involves the formation of a palladium-carbon covalent bond. Palladium is also prominent in carbon-carbon ...
Palladium on carbon. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Palladium on carbon, often referred to as Pd/C, is a form of palladium used as a catalyst. [1] The metal is supported on activated carbon to maximize its surface area and activity.
A hydrogen sensor is a gas detector that detects the presence of hydrogen. They contain micro-fabricated point-contact hydrogen sensors and are used to locate hydrogen leaks. They are considered low-cost, compact, durable, and easy to maintain as compared to conventional gas detecting instruments. [1]
Palladium is a precious metal, often compared with platinum, which has various applications in the chemical and electrical industries, jewelry and dental fields.
The palladium-hydrogen electrode (abbreviation: Pd/H 2) is one of the common reference electrodes used in electrochemical study. [1] Most of its characteristics are similar to the standard hydrogen electrode (with platinum). But palladium has one significant feature—the capability to absorb (dissolve into itself) molecular hydrogen. [2][3]
