| Abstract: | Hot‐wired electrodes : Thin metallic wires (d=25 μm) are covered with a 3 μm layer of single‐walled carbon nanotubes (SWCNTs; see image) by electrophoresis from a suspension containing excess ionic surfactant. A pure SWCNT surface is achieved by heating the electrode in air. Strong differences between covered and bare metallic electrodes occur with in situ heating during electrochemical experiments.  |
