Figure 5
Redox-state dependence of the XAS spectra of trioxalatometalate(III/II) complexes. Top: K3[Co(ox)3] and K4[Co(ox)3] dispersed in cellulose measured at 15 K (Best et al., 2016). Bottom: room-temperature (∼293 K) solution spectra of [Fe(ox)3]3− and [Fe(ox)3]4− obtained by in situ electrogeneration using the XAS-SEC cell. |
