sXAS spectra of CoFe‐(CO₃ ²⁻)‐LDHs and CoFe‐[Cr(C₂O₄)₃]³⁻‐LDHs: A) Co L3‐edge, B) Fe L3‐edge and C) O K‐edge. Spectra of Cr₂O₃, Fe₂O₃, CoO and Li₂Co₂O₄ are included in (A) and (C) as references for high‐spin Co²⁺ and low‐spin Co³⁺, respectively. Spectra of FeO and Fe₂O₃ are included in (B) and (C) as references for high‐spin Fe²⁺ and high‐spin Fe³⁺, respectively.^{[ 54 ]}
