The electrochemistry of surfactants on gold single-crystals and of platinum-gold nanorods

[摘要] A series of Pt-coated gold nanorod (Au NR) electrocatalysts were prepared. STEM images showed that Pt nanodots grew epitaxially on the Au NR surface. A CO blocking technique was used in order to coat Pt in a more controlled, uniform manner. The nanorods were characterised using UV-visible spectroscopy and, after being immobilised onto a supported glassy carbon electrode, with cyclic voltammetry. The CO blocking technique was crucial in enhancing CO electrooxidation and oxygen reduction reaction activity of the nanorods, not only because of the higher coverage of Pt nanodots but also because of their electrocatalytically more active nature.
