  • Porous dendritic platinum tubes as fuel cell electrocatalysts
    Patent number: 8709127
    Abstract: Platinum particles have been formed as porous, hollow tubular dendrites by using silver dendrite particles in a galvanic replacement reaction conducted in an aqueous solution of a platinum compound. The dendritic platinum particles have been found useful as catalysts and particularly useful as a hydrogen-oxidation electrocatalyst and/or an oxygen-reduction catalyst in a polymer electrolyte membrane fuel cell.

  • Alloy nanoparticle synthesis using ionizing radiation
    Patent number: 7998239
    Abstract: A method of forming stable nanoparticles comprising substantially uniform alloys of metals. A high dose of ionizing radiation is used to generate high concentrations of solvated electrons and optionally radical reducing species that rapidly reduce a mixture of metal ion source species to form alloy nanoparticles. The method can make uniform alloy nanoparticles from normally immiscible metals by overcoming the thermodynamic limitations that would preferentially produce core-shell nanoparticles.
