Platinum (Pt)

Platinum is used in diverse catalytic applications. Heraeus offers platinum catalysts for coating of supported catalysts.

Platinum is widely used in petrochemistry for the so-called reforming (“Platforming”). Also, several petrochemical isomerization and cracking processes, as well as certain oxidation reactions run on supported platinum catalysts, too. The reverse reactions are also feasible, e.g. the reduction of benzene to cyclohexane. Platinum is also catalytically active to hydrogenations in synthetic chemistry for the reduction of functional groups – e.g. C=C’s, C=O’s, C=N’s – without hydrogenolysis, and of aromatic nitro compounds to aniline derivatives. A specific example is the reductive synthesis of hydroxylamine (NH2OH) from NO with a Pt catalyst. Furthermore, to "Gas to Liquid" catalysts platinum can be applied as co-catalyst as well as platinum catalysts serve to remove impurities from gases (e.g. carbon monoxide, CO, from hydrogen).
