Growing Pt nanowires as a densely packed array on metal gauze

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

This project describes the synthesis of single-crystal nanowires of Pt directly on the surface of metal gauze made of Pt or W and demonstrates a more attractive approach for the growth of Pt nanowires on functional solid supports. There is evidence that the growth mechanism of the nanowires is correlated to the concentration of the Pt precursor and the surface roughness of the substrate. Electrochemical measurements indicate that the active surface area of the Pt nanowire-coated gauze is about three orders of magnitude greater than the pristine gauze. The results from this research demonstrate a new type of conductive support that can be used as active components for fuel cell applications and as an ideal 3D model catalyst.
