Palladium Nanoparticles -
Palladium nanoparticles are typically ranging from a few up to 100 nm with a large specific surface area. Palladium nanoparticles are of great importance as catalytic materials, as well as for a number of other applications such as hydrogen storage and sensing. Their synthesis has been widely studied and interest in their properties is growing. The high surface-area-to-volume ratio makes nanomaterials highly desirable for use as potential catalysts. Given that palladium is one of the most efficient metals in catalysis, the study of palladium-based materials is hugely important and valuable. As a consequence, nanoparticles of palladium have been heavily studied in a wide range of catalytic applications including hydrogenations, oxidations, carbon–carbon bond formation, and electrochemical reactions in fuel cells. However, it should be noted that the applications of palladium go beyond catalysis. For example, the propensity of palladium to adsorb hydrogen has also led to palladium nanoparticles being utilised in hydrogen storage and sensing applications. Surface functionalized nanoparticles allow for the particles to be preferentially adsorbed at the surface interface using chemically bound polymers. Another application of palladium nanoparticles consists in its use as electron-dense markers for labeling in both transmission and scanning electron microscopy and requires their conjugation to a specific protein.
