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 Elower than E+150 mV and an acidified platinum salt solution having a Pt salt concentration less than 5.0 mmole Lor, in presence of hydrogen, comprising limiting the concentration of Pt salts in the electrolyte to less than 5.0 mmole Land 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.
