Patent number: 8404613Abstract: High-surface-area carbon nanostructures coated with a smooth and conformal submonolayer-to-multilayer thin metal films and their method of manufacture are described. The preferred manufacturing process involves the initial oxidation of the carbon nanostructures followed by immersion in a solution with the desired pH to create negative surface dipoles. The nanostructures are subsequently immersed in an alkaline solution containing non-noble metal ions which adsorb at surface reaction sites. The metal ions are then reduced via chemical or electrical means and the nanostructures are exposed to a solution containing a salt of one or more noble metals which replace adsorbed non-noble surface metal atoms by galvanic displacement. Subsequent film growth may be performed via the initial quasi-underpotential deposition of a non-noble metal followed by immersion in a solution comprising a more noble metal.Type: GrantFiled: February 22, 2010Date of Patent: March 26, 2013Assignee: Brookhaven Science Associates, LLCInventors: Radoslav Adzic, Alexander Harris

Publication number: 20130056359Abstract: An apparatus and method for the synthesis and treatment of electrocatalyst particles in batch or continuous fashion is provided. In one embodiment, the apparatus is comprised of a three-electrode cell which includes a reference electrode, a counter electrode, and a working electrode. The working electrode is preferably a cylindrical vessel having an electrically conductive region. The electrode assembly is introduced into a slurry containing metal ions and a plurality of particles. During operation an electrical potential is applied and the working electrode is rotated at a predetermined speed. When particles in the slurry collide with the electrically conductive region the transferred charge facilitates deposition of an ad-layer of the desired metal. In this manner film growth can commence on a large number of particles simultaneously. This process is especially suitable as a commercial thin film deposition process for forming catalytically active layers on nanoparticles for use in energy conversion devices.Type: ApplicationFiled: March 24, 2011Publication date: March 7, 2013Applicant: BROOKHAVEN SCIENCE ASSOCIATES LLCInventors: Radoslav Adzic, Miomir Vukmirovic

Patent number: 8389387Abstract: Vapor-liquid-solid growth of nanowires is tailored to achieve complex one-dimensional material geometries using phase diagrams determined for nanoscale materials. Segmented one-dimensional nanowires having constant composition display locally variable electronic band structures that are determined by the diameter of the nanowires. The unique electrical and optical properties of the segmented nanowires are exploited to form electronic and optoelectronic devices. Using gold-germanium as a model system, in situ transmission electron microscopy establishes, for nanometer-sized Au—Ge alloy drops at the tips of Ge nanowires (NWs), the parts of the phase diagram that determine their temperature-dependent equilibrium composition. The nanoscale phase diagram is then used to determine the exchange of material between the NW and the drop. The phase diagram for the nanoscale drop deviates significantly from that of the bulk alloy.Type: GrantFiled: January 6, 2010Date of Patent: March 5, 2013Assignee: Brookhaven Science Associates, LLCInventors: Eli Anguelova Sutter, Peter Werner Sutter

Publication number: 20130034803Abstract: Elongated noble-metal nanoparticles and methods for their manufacture are disclosed. The method involves the formation of a plurality of elongated noble-metal nanoparticles by electrochemical deposition of the noble metal on a high surface area carbon support, such as carbon nanoparticles. Prior to electrochemical deposition, the carbon support may be functionalized by oxidation, thus making the manufacturing process simple and cost-effective. The generated elongated nanoparticles are covalently bound to the carbon support and can be used directly in electrocatalysis. The process provides elongated noble-metal nanoparticles with high catalytic activities and improved durability in combination with high catalyst utilization since the nanoparticles are deposited and covalently bound to the carbon support in their final position and will not change in forming an electrode assembly.Type: ApplicationFiled: September 21, 2012Publication date: February 7, 2013Applicant: Brookhaven Science Associates, LLC/Brookhaven National LaboratoryInventor: Brookhaven Science Associates, LLC/Brookhaven
