a, f In situ XANES spectra recorded at the Ni k-edge of NiMoO4 (a) and e-NiMoO4 (f) at different operating potentials from ocp to -0.5 V vs. RHE during the HER process. b, h The corresponding enlarged area of in situ XANES spectra of (a, f). c, g Fourier transformed magnitudes of Ni k-edge of NiMoO4 (c) and e-NiMoO4 (g) EXAFS spectra under various potentials. d, i The coordination number of Ni extracted from EXAFS fitting results of NiMoO4 (d) and e-NiMoO4 (i). e, j Scheme of stability mechanism of NiMoO4 (e) and e-NiMoO4 (j).
