The solid solution between platinum and palladium in nature
(2013-07-15)
Chemical and structural data are reported for platinum-palladium intermediates from two nuggets found at Corrego Bom Sucesso, Minas Gerais, Brazil. Three grains with simple stoichiometries (i.e. PtxPd1 -x with x ∼0.67, ...

Simultaneous determination of platinum and palladium by second derivative spectrophotometry using 3-(2'-thiazolylazo)-2,6-diaminopyridine as chromophore ligand
(Marcel Dekker Inc., 2000)
A second derivative spectrophotometric method has been developed for the determination of palladium and platinum in mixtures. The method is based on the formation of the platinum and palladium complexes with 3-(2- ...
Liquid-Phase Hydrogenation of Crotonaldehyde over Platinum- and Palladium-Based Catalysts
(American Chemical Society, 2009-12-26)
The selective hydrogenation of crotonaldehyde in liquid phase, at a temperature of 353 K and a H2 pressure of 400 kPa, is studied over different palladium- and platinum-based catalysts (Pd−Pb/α-Al2O3, Pd−Zn/α-Al2O3, Pd/ZnO, ...
Botryoidal platinum, palladium and potarite from the Bom Sucesso stream, Minas Gerais, Brazil: Compositional zoning and origin
(Mineralogical Associação Canada, 2002-04-01)
Platinum-Pd nuggets from the Born Sucesso stream alluvium Minas Gerais, Brazil. have been investigated by electron-probe microanalysis. The nuggets attain 1 mm in maximum dimension and have a botryoidal habit, with pronounced ...
