Boosting Lattice Oxygen Oxidation of Perovskite to Efficiently Catalyze Oxygen Evolution Reaction by FeOOH Decoration
Evidences of weakened Ni-O bond. (a) Normalized nickel K-edge XANES spectra. (b) EXAFS Fourier transform (FT) spectra of LNO and Fe-LNO with nickel foil as a reference. (c) In situ Raman spectra of Fe-LNO and LNO in open circuit and 1.23 V vs. RHE.
