Abstract

In this study, platinum was electroplated onto bare Ti substrates (Pt black) and through a porous AAO membrane (Pt nanowires). The morphology of the deposits was observed by scanning electron microscopy. Preferential orientation along the (100) direction into the bulk material was evidenced through XRD analysis, as well as at the nanowire surface by using electrochemical characterization. These highly oriented Pt nanowires exhibited an increased activity for the electrocatalytic oxidation of hydrazine oxidation, as compared to Pt black.
