Under suitable conditions (80 °C [176 °F] and 1 atmosphere), palladium absorbs more than 900 times its own volume of hydrogen.  Palladium reached $2,024.64 per troy ounce ($65.094/g) on January 6, 2020, passing $2,000 per troy ounce the first time.
The remaining 25% of new line palladium supplies come from North America (14%) and other areas such as South America, Zimbabwe, Australia, and other areas of the world (9%).
, Palladium catalysis is primarily employed in organic chemistry and industrial applications, although its use is growing as a tool for synthetic biology; in 2017, effective in vivo catalytic activity of palladium nanoparticles was demonstrated in mammals to treat disease. For the mineralogical properties of palladium, see native element (table).
The technology, dubbed PGClear, works very much like the catalytic converter in a car, Wong told Live Science.
Although contact dermatitis has been reported, data on the effects are limited.
For example, reduction of a mixture of PdCl2(PPh3)2 and PPh3 gives tetrakis(triphenylphosphine)palladium(0):, Another major palladium(0) complex, tris(dibenzylideneacetone)dipalladium(0) (Pd2(dba)3), is prepared by reducing sodium tetrachloropalladate in the presence of dibenzylideneacetone.

Palladium is generally found only in pure form, and along with platinum is found in sulfide concentrations in mafic igneous rocks It is mined in Russia, the USA (Montana), Zimbabwe, Australia, Canada and Finland. A series of palladium compounds can be prepared with the +2 oxidation state; numerous compounds in the +4 state and a few in the 0 state are also known. It is a rare and lustrous silvery-white metal discovered in 1803 by the English chemist William Hyde Wollaston.
A metallic or alloylike hydride is formed from which the hydrogen can be removed by increased temperature and reduced pressure. In 2010 the Nobel Prize in Chemistry was awarded "for palladium-catalyzed cross couplings in organic synthesis" to Richard F. Heck, Ei-ichi Negishi and Akira Suzuki.
Palladium has also developed a great reputation for absorbing hydrogen, which can be as much as 900 times its own volume.
