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. They are also available as a nanofluid through the AE Nanofluid production group. Nanofluids are generally defined as suspended nanoparticles in solution either using surfactant or surface charge technology. Nanofluid dispersion and coating selection technical guidance is also available. Other nanostructures include nanorods, nanowhiskers, nanohorns, nanopyramids and other nanocomposites. Surface functionalized nanoparticles allow for the particles to be preferentially adsorbed at the surface interface using chemically bound polymers. Development research is underway in Nano Electronics and Photonics materials, such as MEMS and NEMS, Bio Nano Materials, such as Biomarkers, Bio Diagnostics & Bio Sensors, and Related Nano Materials, for use in Polymers, Textiles, Fuel Cell Layers, Composites and Solar Energy materials. Nanopowders are analyzed for chemical composition by ICP, particle size distribution (PSD) by laser diffraction, and for Specific Surface Area (SSA) by BET multi-point correlation techniques. Novel nanotechnology applications also include Quantum Dots. High surface areas can also be achieved using solutions and using thin film by sputtering targets and evaporation technology using pellets, rod and foil.. 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. Palladium Nano Particles are generally immediately available in most volumes. Additional technical, research and safety (MSDS) information is available.
Palladium is a Block D, Group 10, Period 5 element. The number of electrons in each of Palladium's shells is 2, 8, 18, 18 and its electronic configuration is [Kr] 4d10. In its elemental form palladium's CAS number is 7440-05-3. The palladium atom has a radius of 137.6.pm and it's Van der Waals radius is 163.pm. Palladium is a member of the platinum group of metals. It is an excellent hydrogenation and dehydrogenation catalyst and available in many Organo-metallic forms for this purpose. It is alloyed with gold, silver, iridium and other platinum group elements and used in jewelry. The metal is used in dentistry, watch making, and in making surgical instruments and electrical contacts. Platinum is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Palladium was first discovered by William Hyde Wollaston in 1803. See Palladium research below. Palladium was first discovered by William Hyde Wollaston in 1803. See Palladium research below.
