Nanotubes with an iron will: Iron oxide nanoparticles on N- CNTs show enhanced electrocatalytic CO2 reduction compared to oxidized CNTs. Two types of chemisorption sites have been determined by applying microcalorimetry: irreversible sites at the uncoordinated sites of the facets (top HRTEM image) and reversible sites at the hydrated oxide surface of the small nanoparticles (bottom STEM image). The reversible sites are correlated to the enhancement of the catalytic performance.
