Palladium Oxide (PdO) Nanoparticles – Properties, Applications

Nanoparticles exhibit unexpected behavior due to the altered atomic and molecular properties of basic elements. This article will elaborate on the properties and applications of palladium oxide nanoparticles.

Palladium oxide (PdO) nanoparticles are available in the form of dispersions, coatings, transparent and high purity particles. Some of the synonyms of palladium oxide are panaxan, ketopalladium, oxopalladium and palladium monoxide. Palladium belongs to Block D, Period 5 while oxygen belongs to Block P, Period 2 of the periodic table.
