This metal is sometimes combined with Rhodium to make a thermocouple and can be oxidized to form Adams' Catalyst.
This metal is sometimes combined with Rhodium to make a thermocouple and can be oxidized to form Adams' Catalyst. Scientists are now trying to replace its use with nanonickel and are growing it on top of palladium nanocrystals to obtain more efficient fuel cell catalysts. It sometimes is found with Iridium in nature, and their combination is used to define a kilogram. Name this very expensive metal appearing just before Gold on the Periodic Table with atomic symbol Pt.
