  Abstract

  A unique materials’ methodology enables the doping of metals with functional molecules, polymers, enzymes, and nanoparticles. The resulting materials have either the combined properties of the metal and the dopants, or new, sometimes synergetic properties that are not found in the separate components, emerge. Metals that have been doped so far include gold, silver, copper, iron, gallium, palladium, platinum, and several alloys. Numerous applications have been demonstrated including catalysis, biocatalysis, bioactivity, electrochemistry (including new type of batteries), corrosion resistance, induction of chirality, tailoring unconventional properties to metals, and more. Doping of metals and adsorption on them are completely different processes, doping being a 3D event, while adsorption is a 2D process. Thus, practically all special properties and functionalities that have been demonstrated are apparent only in the doped case. Here, I will highlight the progress made in this field in the past three years, including tuning the work function, metallic conductive luminescent film, novel cathode electrode of fuel cells, and the advanced characterization of doping metals with synchrotron XRD, X-ray Absorption Spectra (XAS) and Inelastic Neutron Scattering (INS).
