Adams' catalyst, also known as platinum dioxide, is usually represented as platinum(IV) oxide hydrate, PtO 2 •H 2 O. It is a catalyst for hydrogenation and hydrogenolysis in organic synthesis . [ 1 ]
Platinum is a chemical element; it has symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Its name originates from Spanish platina, a diminutive of plata "silver". [7] [8] Platinum is a member of the platinum group of elements and group 10 of the periodic table of ...
Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium. It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume.
Platinum black (Pt black) is a fine powder of platinum with good catalytic properties. The name of platinum black is due to its black color. It is used in many ways; as a thin film electrode, a fuel cell membrane catalyst, or as a catalytic ignition of flammable gases for "self-lighting' gas lamps, ovens, and stove burners.
Platinum's current spot price is $1,004 an ounce, according to financial services company FactSet, which means that Costco's price is about 8% higher than the market value. Michigan voters share ...
Platinum on carbon, often referred to as Pt/C, is a form of platinum used as a catalyst. [1] The metal is supported on activated carbon in order to maximize its surface area and activity . Uses
[3] [4] In this application, Rh–Pt oxide is superior to other group 10 catalysts such as platinum dioxide. Furthermore, the catalyst can be used to carry out the reaction with minimal losses of oxygen containing functional groups via hydrogenolysis. [5] [6] [7]
