  • Method and system for preparation of highly porous and preferentially-oriented {100} platinum nanowires and thin films
    Patent number: 9108843
    Abstract: A method for preparation of highly porous and preferentially-oriented {100} platinum on a substrate by electrodeposition in a deposition bath, comprising using a deposition potential Edep lower than ERHE+150 mV and an acidified platinum salt solution having a Pt salt concentration less than 5.0 mmole L?1 or, in presence of hydrogen, comprising limiting the concentration of Pt salts in the electrolyte to less than 5.0 mmole L?1 and controlling the temperature of the electrolyte. Preferentially-oriented {100} platinum nanowires and thin films, comprising Pt{100} in a range between about 20 and about 60% and having a roughness factor of at least 50 are produced.
    Type: Grant

    Date of Patent: August 18, 2015
    Assignee: INSTITUT NATIONAL DE LA RECHERCHE SCIENTIFIQUE
    Inventors: Erwan Bertin, Sébastien Garbarino, Daniel Guay, Manuel Martin, Alexandre Ponrouch
