Precision work: The spatially confined deposition of Fe nanoparticles on a glassy carbon surface using a droplet cell allows the catalytic growth of carbon nanotubes (CNTs) on the locally confined Fe‐modified areas in a chemical vapour deposition process. These CNTs, partially decorated with Pt nanoparticles, are evaluated for their activity in the oxygen reduction reaction (see picture).
