We report Pt nanowire electrodes fabricated by means of electrodeposition method as a function of molecular weight of polyvinylpyrrolidone (PVP-L and PVP-H). The higher molecular weight of PVP results in a smaller grain size of Pt nanophases in the electrode. The Pt nanowire array electrode electrodeposited with PVP-H shows the smallest gain size of Pt and an excellent catalytic activity for methanol electrooxidation in comparison with pure Pt nanowire array electrodes electrodeposited without PVP and with PVP-L (C) 2010 Elsevier B.V.
