Several papers were concerned with the detailed atomic arrangement at clean surfaces of platinum group metals. G. Comsa, of KFA Jülich, has scattered helium atoms from a clean platinum surface cut at a small angle to the (111) plane and found direct evidence for an upward bending of the terrace planes of atoms in the vicinity of the downward ...

US4431750A - Platinum group metal catalyst on the surface ...

Platinum or other platinum-group metals can be deposited substantially on the surface only of pellets of a refractory catalyst support by impregnation with an aqueous solution of such as hexammonium platinum tetrasulfite. The resulting catalysts contain relatively small total amounts of platinum-group metal positioned primarily at the surface, yet are as highly active as catalysts uniformly ...

Platinum-Group Metals Plating Surface Engineering ...

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.
