Line Plot from Scientific Research

Fitted FT-EXAFS spectra of NiK-edge in Ba8Ni6Ge40/FTO electrode after OER CA at 1.55 V versus RHE. Inset: digital images showing electrode color at the corresponding reaction states; at 1.0 V versus RHE (inset in f), the electrode film is transparent. In d-f, the indicated reduced distances are about 0.3 A smaller than the precise distances determined by EXAFS fits (see TableS5).
