Abstract

A catalyst consisting of atomic iron embedded in a new hierarchical carbon matrix was synthesised, and this catalyst exhibited superior performance in CO2 electroreduction. Bamboo-like carbon nanotubes were catalytically grown by Fe3C nanocrystals on graphene co-doped with atomic iron and nitrogen by a new approach of electrochemical oxidation of graphene films in an FeCl4-based ionic liquid followed by annealing. The highly selective generation of CO from CO2 was achieved at a low overpotential of 0.55 V with a maximum CO faradaic efficiency of ∼95% for over 12 h.
