Application
Platinum is a white noble metal that looks very much like metallic silver found in copper ore. The name platinum comes from the Spanish word plata, meaning silver. Platinum compounds were used in the platinum printing process and for toning silver images. Nanoscale platinum powders possess improved reaction rates compared to bulk powders owing to their high surface area. Platinum nanopowders have found use in applications including in fuel cells and oxidation catalysts.
