Aligned carbon nanotubes with built-in FeN4 active sites for electrocatalytic reduction of oxygen.
The electrocatalytic site FeN4, which is active towards the oxygen reduction reaction, is incorporated into the graphene layer of aligned carbon nanotubes prepared through a chemical vapour deposition process, as is confirmed by X-ray absorption spectroscopy and other characterization techniques.
