Article Synopsis
- A new operando soft X-ray absorption spectroscopy technique was developed to analyze the electronic structures of electrode materials under controlled temperature and atmosphere during electrochemical reactions.
- This technique was applied to study the La NiO dense-film electrode during the oxygen reduction reaction, revealing significant changes in the O K-edge X-ray absorption spectra with different oxygen partial pressures and electrical potentials.
- The findings highlighted that the pre-edge peak in the O K-edge spectra, associated with Ni 3d-O 2p hybridization, varied with cathodic and anodic polarization, confirming the electronic structural changes in the electrode material.
