Carbon surface chemistry drives speciation and reactivity of cationic Fe species in CO<sub>2</sub> activation: a HERFD-XANES and valence-to-core XES study
HERFD-XANES, VtC-XES and electroanalysis reveal how Fe coordination dictates CO 2 reactivity, guiding catalyst design. N-coordinated Fe–OH on N-doped graphene activates CO 2 to form bicarbonates, unlike FeTCPP, where direct Fe–CO 2 coordination occurs.
