摘要
A method for preparation of highly porous and preferentially-oriented {100}platinum on asubstrate by electrodeposition in a deposition bath, comprising using adeposition potential E dep lower than E RHE+ 150 mV and an acidified platinum salt solution having a Pt saltconcentration less than 5.0 mmole L-1 or, inpresence of hydrogen, comprising limiting the concentration of Pt salts in theelectrolyte to less than 5.0 mmoleL-1 and controlling the temperature of the electrolyte. Preferentially-oriented {100} platinum nanowires and thinfilms, comprising Pt{100} in a range between about 20 and about 60% and havinga roughness factor of at least50 are produced.
