  2. Adams' catalyst - Wikipedia

    en.wikipedia.org/wiki/Adams'_catalyst

    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 ]

  3. Platinum on carbon - Wikipedia

    en.wikipedia.org/wiki/Platinum_on_carbon

    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

  4. Catalysis - Wikipedia

    en.wikipedia.org/wiki/Catalysis

    A true catalyst can work in tandem with a sacrificial catalyst. The true catalyst is consumed in the elementary reaction and turned into a deactivated form. The sacrificial catalyst regenerates the true catalyst for another cycle. The sacrificial catalyst is consumed in the reaction, and as such, it is not really a catalyst, but a reagent.

  5. Catalytic reforming - Wikipedia

    en.wikipedia.org/wiki/Catalytic_reforming

    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]

  6. Organoplatinum chemistry - Wikipedia

    en.wikipedia.org/wiki/Organoplatinum_chemistry

    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.

  7. Catalytic oxidation - Wikipedia

    en.wikipedia.org/wiki/Catalytic_oxidation

    Typical catalysts are platinum, and redox-active oxides of iron, vanadium, and molybdenum. In many cases, catalysts are modified with a host of additives or promoters that enhance rates or selectivities. Important homogeneous catalysts for the oxidation of organic compounds are carboxylates of cobalt, iron, and manganese

  8. Platinum - Wikipedia

    en.wikipedia.org/wiki/Platinum

    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 ...

  9. Catalytic heater - Wikipedia

    en.wikipedia.org/wiki/Catalytic_heater

    In addition to the larger catalytic heaters there are also small hand warmer or pocket heaters that use a catalyst combustion unit. Current units use a glass fiber substrate coated with platinum. Cheaper units may use other catalysts that don't work as well. Some older units used asbestos substrates.
