Palladium (Pd) Nanoparticles, nanodots or nanopowder are black spherical high surface area metal particles. Nanoscale Palladium Particles are typically 20 - 100 nanometers (nm) with specific surface area (SSA) in the 1 – 3 m 2 /g range. Nano Palladium Particles are also available in Ultra high purity and high purity and coated and dispersed forms. Applications for Palladium nanocrystals include numerous uses in catalysts (including catalytic converters), electrocatalysts, chemical synthesis and for their affinity for hydrogen, in a nucleation layer of palladium, ruthenium or rhenium nanoparticles in-between a copper pad surface to create an electrical connection that has superior diffusion barrier and adhesion properties and as a Magnetic Nanopowder, in environmental remediation to remove trichloroethene or TCE, from TCE contaminated ground water (also using gold palladium nanoparticles and on a catalytic membrane) in polymer membranes to create Active Polymer Membranes and in other coatings, plastics, nanofiber and textiles and in nanowire and other catalysis applications.
