The competition is gaining on platinum as a catalyst for hydrogen fuel cells. Levi,B.G. Physics Today . 2009Carrasco, J.; Michaelides, A.; Forster, M.; Haq, S.; Raval, R.; Hodgson, A. A one-dimensional ice structure built from pentagons. Nat. Mater. 2009 , 8 , 427–431....
Platinum is also used as a catalyst to make chemicals like silicone, nitric acid and benzene. In fact, the six platinum group metals (iridium, palladium, platinum, rhodium, ruthenium and osmium) are all known for their impressive catalytic skills (meaning these metals increase the rate of ...
Reduced graphene oxide (RGO)-supported platinum (Pt) catalyst was prepared by simple ethylene glycol (EG) reduction and used for hydrogenation of nitroarenes. Characterizations showed that EG as a reductant exhibited more advantages than the widely used hydrazine hydrate to fabricate monodispersed, sm...

Platinum (Pt) has found wide use as an electrocatalyst for sustainable energy conversion systems1,2,3. The activity of Pt is controlled by its electronic structure (typically, the d-band centre), which depends sensitively on lattice strain4,5. This dependence can be exploited for catalyst desi...
Bis(dichlorosilyl)methanes 1 undergo the two kind reactions of a double hydrosilylation and a dehydrogenative double silylation with alkynes 2 such as acetylene and activated phenyl-substituted acetylenes in the presence of Speier's catalyst to give 1,1,3,3-tetrachloro-1,3-disilacyclopentanes 3...
Platinum dioxide, also known as Adams catalyst, is a dark brown powder, a hydrated form of platinum (IV) oxide (PtO2), produced by heating chloroplatinic acid (H2PtCl6) with sodium nitrate (NaNO3). Platinum nitrate is produced, and this decomposes to Platinum (IV) oxide with evolution of...
