The platinum group metals are well suited for use at extremely high temperatures under mechanical loads and simultaneous corrosive attack. They have high melting points, excellent chemical stability and are highly resistant to oxidation. When using these materials in the design of components it is necessary to have data available on their elastic properties as a function of temperature.

There are between 3-7 grams of platinum group metals in a standard catalytic converter, but the amount varies based on manufacturer and model. In terms of the extent to which they are used, there are generally around 3 to 7 grams of PGMs in a standard catalytic converter. However, the amount varies depending on the size of the unit.

Introduction. Platinum is a chemical element with symbol Pt and atmomic number 78.The electron configuration is [Xe] 4f 14 5d 9 6s 1.Its crystal structure is face-centered cubic (fcc, see Fig. 1), and the lattice constant is 3.9239 Å[1].. The target for this computation experiment is to use density functional theory (DFT) to evaluate the energy of fcc lattice at different lattice constants.

The electroplating of platinum-group metals (PGMs) from aqueous electrolytes for engineering applications is limited principally to palladium and, to a lesser extent, to platinum, rhodium, and thin layers of ruthenium. This article provides a discussion on the plating operations of these PGMs along with the types of anodes used in the process.

Extensive research efforts have been made on platinum group metal (PGM)-free electrocatalysts for oxygen reduction reaction, with the aim of lowering the cost hurdle of acidic polymer electrolyte fuel cells (PEFCs). While the activity and durability of PGM-free catalysts have been boosted, the PEFC performance relies also on the electrode structure at the membrane electrode assembly (MEA) level.
