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] This dark brown powder is commercially available.
[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]
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
Organoplatinum chemistry is the chemistry of organometallic compounds containing a carbon to platinum chemical bond, and the study of platinum as a catalyst in organic reactions. [ 1 ] [ 2 ] [ 3 ] Organoplatinum compounds exist in oxidation state 0 to IV, with oxidation state II most abundant.
However, independently of the crude oil used in the refinery, all catalysts require a maximum final boiling point of the naphtha feedstock of 180 °C. Normally, the catalyst can be regenerated perhaps 3 or 4 times before it must be returned to the manufacturer for reclamation of the valuable platinum and/or rhenium content. [12] [page needed]

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 is the most promising candidate among pure metals for application in DMFCs. Platinum has the highest activity toward the dissociative adsorption of methanol. However, pure Pt surfaces are poisoned by carbon monoxide, a byproduct of methanol oxidation. Researchers have focused on dispersing nanostructured catalysts on high surface area ...
